Seeing the message "An automated WordPress update has failed to complete" in your WordPress dashboard can be worrying, especially if you’re unsure whether the update has affected your website.
WordPress normally handles many updates automatically, but sometimes something goes wrong during the process.
The problem could be as simple as a temporary connection failure or insufficient disk space. In other cases, it may involve file permissions, server configuration or an interrupted installation.
The good news is that a failed update doesn’t always mean your website is broken.
In this guide, we’ll explain what the warning means, how to fix a failed WordPress automatic update, and what to check before making changes that could affect your website.
We’ll start with straightforward checks that most website owners can carry out, then cover more technical troubleshooting for persistent problems.
What Does the Failed WordPress Update Message Mean?
You may see a warning similar to this in your WordPress dashboard:
"An automated WordPress update has failed to complete – please attempt the update again now."
This particular message relates to WordPress’s automatic core update process.
It indicates that WordPress has recorded an unsuccessful update attempt or detected an incomplete update condition.
However, it doesn’t tell you exactly what went wrong.
An update might fail before WordPress starts replacing files, while files are being copied, or during a later stage of the process.
That distinction matters because a failed download and an interrupted installation may require very different solutions.
Does the warning mean your website is broken?
Not necessarily.
Your website might still be working normally, with WordPress running the previous version.
Alternatively, an update could have been interrupted after some files were replaced. This is more serious because the installation may contain files from different versions.
WordPress can also retain a warning after an unsuccessful attempt, even if the version shown in the dashboard appears current.
Don’t assume the update succeeded or failed completely based on the warning alone.
Check the installed version, website functionality and any available error details before deciding what to do.
Failed updates, maintenance mode and update locks
There are three related WordPress messages worth distinguishing.
| Message | What it usually means |
|---|---|
| An automated WordPress update has failed to complete | WordPress has recorded a failed core update or incomplete update condition. |
| Briefly unavailable for scheduled maintenance | WordPress is displaying maintenance mode, possibly because an update hasn’t finished or was interrupted. |
| Another update is currently in progress | WordPress has detected an update lock or another update process may still be running. |
These messages don’t all have the same solution.
For example, removing a stale maintenance file may restore access to a website, but it won’t necessarily repair an incomplete WordPress installation.
Likewise, deleting an update lock without checking whether an update is still active could interfere with another process.
The safest approach is to establish what’s happening before changing anything.
What to Do Before Troubleshooting
Before attempting another update, take a few minutes to assess the situation.
Check whether your website is working
Open your website in a private browser window and check a few important pages.
If possible, confirm that you can:
- Load the homepage and key pages.
- Access the WordPress dashboard.
- Navigate between pages without errors.
- Use important forms and interactive features.
- Access customer accounts or checkout functionality, where applicable.
You don’t need to test every feature immediately, but you should establish whether the website is broadly functioning.
If the site is completely unavailable, displaying a critical error or behaving unpredictably, avoid repeatedly triggering updates.
An interrupted update affecting core files may need more careful recovery.
Check whether an update is still running
An update can temporarily make parts of WordPress unavailable.
If you’ve only just noticed the problem, check whether the hosting dashboard or another administrator shows an update in progress.
Don’t launch another update while the first one is still running.
If you’re uncertain whether an update process has finished, ask your hosting provider to confirm before proceeding.
Verify that you have a recoverable backup
Before attempting any repair, make sure you have a reliable backup of your website.
A complete WordPress recovery normally requires both the website files and database.
If your backup system is accessible, check when the most recent successful backup was taken and whether it includes everything you may need.
Ideally, you should have a known-good recovery point from before the failed update.
It may also be useful to preserve the website’s current state for investigation, particularly if the failure has already changed some files.
Keep in mind that restoring an older database on an active website can remove newer orders, accounts, enquiries or content.
Don’t overwrite your only good backup or restore an older database without understanding what newer information could be lost.
If your hosting provider manages backups, ask them to confirm the available restore points before making further changes.
How to Fix a Failed WordPress Automatic Update
The following steps move from simple checks to more involved troubleshooting.
Work through them in order, stopping if you discover a problem that requires your hosting provider or developer.
Step 1: Open the WordPress Updates screen
If you can access your WordPress dashboard, go to:
Dashboard > Updates
Look for the installed WordPress version and any available core update.
You can also visit Tools > Site Health > Info to review information about your WordPress installation and hosting environment.
The Updates screen helps you determine whether WordPress still offers a newer version.
If the website appears to be running the latest available version but the warning remains, don’t simply assume everything is fine.
A failed installation can sometimes leave files inconsistent even when the reported version looks correct.
That situation may require additional checks.
Step 2: Look for error information
Check whether WordPress or your hosting provider has given you more detail about the failed update.
Useful information can include:
- WordPress administrator notification emails.
- An error message shown during an attempted update.
- Hosting dashboard alerts.
- Relevant server or PHP error logs.
- Available disk space warnings.
- File access or permission errors.
If you received an email about a failed automatic update, keep it.
Some WordPress notifications distinguish an ordinary failure from a more serious problem that may have occurred after the update started replacing files.
The more specific the error information, the easier it will be to investigate the cause.
Step 3: Check WordPress Site Health
Navigate to:
Tools > Site Health
Review the Status tab for problems that might affect background updates.
For example, WordPress can report issues with:
- Background updates not working as expected.
- Communication with WordPress.org.
- HTTP requests being blocked.
- Server configuration.
- Outdated PHP versions or other compatibility concerns.
You can also open the Info tab to inspect technical information about your installation.
Site Health won’t diagnose every failed update, but it can help identify configuration problems before you retry.
If you see a warning about server connectivity or filesystem access, investigate that first.
Step 4: Retry the WordPress update when it’s safe
If the website is functioning normally, no update is running, you have a verified backup and no serious error has been identified, you may be able to retry the update through WordPress.
Return to Dashboard > Updates.
If WordPress offers an appropriate Update Now button, use the normal dashboard process and allow it to finish.
Follow any database update prompt that WordPress displays afterwards.
Then return to the Updates screen to check the result.
Don’t repeatedly click the update button if the same failure occurs.
A second failure suggests that the underlying problem needs investigating rather than another attempt under identical conditions.
If the website is already showing critical errors or there are signs of an incomplete core installation, seek help before retrying.
Step 5: Check important functionality afterwards
Once the update reports success, check the installed WordPress version and visit the public website again.
Review the features most important to your site, such as:
- Homepage and navigation.
- Contact forms.
- Login and account pages.
- Important plugins and theme functionality.
- WooCommerce basket and checkout, if applicable.
- Any features that were previously showing errors.
If your website uses caching, you may need to clear the appropriate caches to see the latest changes.
Also check whether the failed-update warning has disappeared.
A successful update is encouraging, but the final website checks help confirm that important functionality still works.

Common Reasons WordPress Automatic Updates Fail
If WordPress continues reporting a failed update, the next step is to investigate why.
Several server and configuration problems can interfere with the update process.
Insufficient disk space
WordPress needs temporary storage to download, extract and install update files.
If your hosting account or server is running low on disk space, an update may fail.
Check your hosting dashboard for available storage and any warnings about disk limits.
Large backups, unnecessary staging copies and accumulated log files can contribute to storage problems.
However, don’t start deleting unfamiliar files or database backups just to create space.
Ask your hosting provider to help identify what can safely be removed.
Once sufficient storage is available, the update may be able to complete successfully.
Incorrect file permissions or ownership
WordPress needs suitable filesystem access to replace or create files during an update.
If the relevant files or directories aren’t writable by the process handling the update, WordPress may be unable to continue.
This can happen after hosting migrations, manual file uploads or changes to server ownership.
You may encounter advice suggesting permissions such as 755 for directories and 644 for files.
Although these are common settings, they aren’t a universal solution.
The correct permissions depend on your hosting configuration, and file ownership is just as important.
Changing permissions across an entire website without understanding the server setup can create security or functionality problems.
If WordPress reports that files can’t be written, ask your hosting provider to check ownership and permissions.
Our guide to fixing WordPress file permissions issues explains the subject in more detail.
Server connection or download problems
WordPress needs to communicate with WordPress.org to check for and download official core updates.
If the hosting server can’t reach the required services, the update may fail before installation begins.
Potential causes include:
- Temporary network problems at the hosting provider.
- DNS resolution failures.
- Firewall restrictions on outbound connections.
- SSL or certificate validation problems.
- Temporary problems downloading an update package.
This is different from your own computer’s internet connection.
An automatic background update runs on the hosting server, so testing the speed of your home broadband connection won’t usually help diagnose the problem.
Check Site Health for connectivity warnings or ask your hosting provider to investigate outbound connections.
PHP errors, resource limits or timeouts
WordPress updates run using PHP and the resources made available by your server.
A process may fail if it encounters a fatal error, runs out of available memory or exceeds a relevant execution limit.
A busy or heavily restricted hosting environment may also contribute to update problems.
The best way to investigate is to examine the relevant server and PHP error logs around the time of the failed update.
Tools such as Google PageSpeed Insights are designed for evaluating website performance, not diagnosing failed PHP update processes.
If server resources are the cause, your hosting provider can advise whether configuration changes or a more suitable hosting environment are needed.
Plugin, theme or compatibility problems
Some plugins, themes or custom code can interfere with WordPress processes or cause problems after an update.
However, a plugin conflict isn’t automatically the cause of every failed core update.
Look for evidence in error messages or logs before making major changes.
Avoid deactivating every plugin on a live website as your first troubleshooting step.
Doing so can disrupt forms, checkout systems, memberships and other important features.
Instead, investigate suspected conflicts selectively.
Where possible, reproduce the problem in a WordPress staging environment.
Our guide to fixing WordPress plugin problems covers a safer approach to identifying conflicts.
Incomplete or damaged update files
Sometimes an update package downloads incompletely or WordPress is interrupted while replacing files.
The installation may then contain missing or inconsistent core files.
Depending on when the failure occurred, WordPress may still load normally, display errors or become inaccessible.
This isn’t something you should attempt to fix by uploading a random collection of files over your existing installation.
A developer can verify the installed core files and, if necessary, complete a controlled reinstall or manual update using the official WordPress instructions.
How to Fix WordPress Stuck in Maintenance Mode
During certain updates, WordPress temporarily places the website into maintenance mode.
Visitors may see:
"Briefly unavailable for scheduled maintenance. Check back in a minute."
Normally, WordPress removes this maintenance state when the update finishes.
However, if the process is interrupted, a maintenance file may remain behind.
What is the .maintenance file?
WordPress uses a hidden file called .maintenance in the WordPress installation directory.
This is normally the same directory that contains wp-admin, wp-content and wp-includes.
While the maintenance file is active, WordPress may show a temporary maintenance message instead of the normal website.
If the update ends unexpectedly, the file can sometimes remain in place.
When can you remove the file?
First, confirm that no update is currently running.
If the update has stopped and the maintenance file is stale, you can use your hosting file manager or an appropriately configured SFTP connection to locate it.
You may need to enable the option to display hidden files, since its name begins with a full stop.
Once you’ve confirmed the file is no longer needed by an active update process, remove the stale .maintenance file.
Avoid deleting similarly named or unfamiliar files.
If you’re unsure whether an update is still active, ask your hosting provider before proceeding.
What should you check afterwards?
Removing the file may restore normal access to your website.
However, clearing maintenance mode doesn’t mean the failed update has been repaired.
Return to WordPress and check:
- Whether you can access the dashboard.
- Which WordPress version is installed.
- Whether an update is still required.
- Whether the website has any new errors.
- Whether the interrupted update needs to be completed.
If WordPress is still failing or important files appear to be missing, stop and investigate before attempting further updates.
WordPress provides official guidance on removing a stale maintenance file and completing an interrupted update.
Advanced Troubleshooting for Persistent Update Failures
If the normal checks haven’t resolved the problem, more detailed investigation may be necessary.
These steps are best handled by someone comfortable working with WordPress hosting and server tools.
Review PHP and server error logs
Hosting and PHP error logs may reveal exactly why the update stopped.
Look for messages recorded around the time of the failed update.
These might identify:
- A fatal PHP error.
- An exhausted memory limit.
- A filesystem permission error.
- A timed-out process.
- A failed download or blocked connection.
Relevant logs are generally more useful than guessing which plugin or setting caused the problem.
WordPress also provides debugging options, but these should be configured carefully.
Don’t enable public error displays or expose potentially sensitive debugging information on a live website.
The official WordPress debugging documentation explains the available options.
Verify WordPress core files
Developers can use WP-CLI to inspect a WordPress installation.
For example, the command:
wp core verify-checksums
compares installed WordPress core files with the official checksums for the relevant WordPress version.
This can help identify missing or unexpectedly modified core files.
However, a checksum failure isn’t automatically proof of malware, and a successful check doesn’t establish that the entire website is working correctly.
The command also doesn’t verify your database, plugins, themes or uploads.
For a more detailed investigation, developers should confirm that the expected WordPress version and language match the installed files.
See the official WP-CLI checksum verification documentation.
Check update locks and background processing
WordPress uses locks to prevent overlapping update processes.
An update may temporarily be unavailable because another update is already running.
In other cases, an interrupted process may leave behind a stale lock.
Don’t immediately delete update-related database records or disable scheduled tasks simply to clear the message.
First, check whether a process is active and review the available logs.
Developers can also investigate WordPress’s background task execution and any update restrictions imposed by hosting or configuration settings.
Consider a controlled manual WordPress update
If the dashboard update repeatedly fails, a manual update may be necessary.
This should be a deliberate recovery process, not a first step.
Before proceeding:
- Verify a recent, restorable backup of files and database.
- Confirm the intended WordPress version.
- Check PHP and database compatibility.
- Identify any custom files or deployment requirements.
- Follow the official WordPress file replacement procedure.
- Complete any required WordPress database upgrade.
- Test the website after the update.
It’s especially important to protect your existing wp-content directory, wp-config.php and database.
Do not replace or delete these indiscriminately.
WordPress’s official manual update guide explains the procedure in detail.
If you’re unfamiliar with updating WordPress files directly, ask your hosting provider or a WordPress developer to perform the recovery.
Know when to restore a backup
Sometimes restoring a known-good version is the safest way to recover from a serious failed update.
However, a restore can have consequences.
For example, replacing an active WooCommerce database with an older backup could remove orders placed since that backup was taken.
A developer should determine whether the problem requires restoring core files, selected components or the full website.
Where possible, preserve newer production data rather than overwriting it unnecessarily.
For a website that handles transactions, bookings or memberships, plan the recovery particularly carefully.
How to Prevent Future WordPress Update Failures
Not every update problem is preventable, but regular maintenance can reduce the risk and make recovery easier.
Keep reliable backups
Maintain recent backups of your WordPress files and database.
Store copies separately from the live hosting environment and periodically verify that they can be restored.
A backup is most useful when you know it is complete and can recover the website when needed.
Use staging for important changes
A staging site lets you test updates and changes separately before applying them to production.
This is particularly helpful for custom websites, major WordPress updates and sites with complex plugin integrations.
For active WooCommerce or membership websites, remember that staging data may become outdated while the live website continues receiving orders and users.
Don’t blindly overwrite production with an older staging database.
Keep WordPress and its hosting environment maintained
Review WordPress, plugin and theme updates regularly.
Monitor available disk space, supported PHP versions, backups and important website functionality.
If automatic updates are enabled, make sure someone is reviewing the results rather than assuming they always succeed.
For more guidance, read Should You Enable WordPress Automatic Updates?.
Monitor for problems after updates
Check important pages and business-critical features after significant updates.
Uptime monitoring can help identify availability problems, but it won’t detect every broken form, layout or checkout issue.
Regular functional checks are still valuable.
A planned maintenance process can make update failures easier to detect, investigate and resolve before they become larger problems.
Frequently Asked Questions
Is it safe to retry a failed WordPress update?
Often, yes, provided the website is functioning normally, no other update is running and you have a verified backup.
However, you should investigate first if the website is showing critical errors, the update appears partially installed or WordPress repeatedly reports the same failure.
Don’t keep retrying without understanding why the previous attempt failed.
Can a failed WordPress update break my website?
Yes, although not every failed update causes a problem.
Some failures happen before WordPress changes any files.
Others occur after the update process has started replacing core files, which can leave the installation in an inconsistent state.
Check both the installed version and website functionality to understand the impact.
Does deleting .maintenance fix a failed update?
Not necessarily.
Removing a stale .maintenance file can clear the maintenance-mode screen after an interrupted update.
It doesn’t automatically replace missing WordPress files, correct permissions or complete the original update.
Always confirm that no update is running before removing the file, then check the website and complete any unfinished update.
What if WordPress says another update is in progress?
First, check whether an update is genuinely running.
If an update was recently interrupted, a temporary lock may remain.
Avoid deleting locks or forcing another update without checking the process first.
Your hosting provider or developer can investigate whether the lock is stale and what action is appropriate.
Why does the warning remain when WordPress appears up to date?
WordPress can record information about failed core update attempts.
Depending on how the failure occurred, the warning may remain even if the version shown in the dashboard appears current.
A developer may need to check the update history and verify core file integrity.
Don’t simply remove the warning without establishing whether the installation is complete.
Can automatic WordPress updates be disabled?
Yes, WordPress provides ways to configure automatic update behaviour.
However, disabling updates doesn’t resolve the underlying cause of a failed update.
It also means you’ll need a reliable alternative process for applying important security and maintenance releases.
Our guide to WordPress automatic updates explains the considerations.
Should I contact my hosting provider or a WordPress developer?
Contact your hosting provider if the problem involves server storage, file ownership, filesystem access or connectivity.
A WordPress developer can help investigate incomplete core updates, plugin conflicts, custom code and recovery procedures.
If your website is offline or important functionality has stopped working, it’s sensible to seek help rather than experimenting with potentially disruptive fixes.
Get Your WordPress Website Working Again
A failed WordPress automatic update doesn’t always mean your website is damaged, but it’s worth investigating before attempting further changes.
Start by checking whether the website works, confirm the installed version and look for any useful error messages.
Make sure you have a recoverable backup before retrying the update or making changes to server files.
If the problem continues, investigate the actual cause rather than repeatedly applying the same fix.
The goal isn’t simply to remove the warning. It’s to make sure WordPress is correctly updated and your website is functioning as it should.
If a failed update has left your website broken or you’re unsure how to recover safely, our Website Repair service can help investigate and resolve the problem.
For ongoing WordPress updates, backups and routine checks, explore our WordPress Maintenance service.
With a reliable update and recovery process in place, you can reduce avoidable problems and keep your website properly maintained.
