Sound good? Then let‘s dive in and get this pesky error squared away together!

What Causes the "Another Update is Currently in Progress" Error in WordPress?

Before we jump into how to fix the "Another update is currently in progress" error, it helps to understand why it happens in the first place.

Here‘s the deal: whenever you start an update through the WordPress admin dashboard (whether that‘s updating WordPress core, a plugin, or a theme), WordPress adds a temporary .lock file to your site‘s database.

Specifically, it creates a row called "core_updater.lock" in the wp_options database table (or prefix_options if you‘ve changed your database prefix).

This lock file basically says "Hey, I‘m working on an update over here! Hold off on starting anything else until I‘m done."

It‘s a safety precaution WordPress takes to prevent multiple updates from running simultaneously and potentially conflicting with or corrupting each other. Makes sense, right?

Normally, this lock gets removed automatically as soon as the update finishes – usually within a few seconds to a couple minutes. But sometimes, the lock file doesn‘t get cleaned up properly and stays in the database even after the update completes.

That‘s when you see the dreaded "Another update is currently in progress. Please try again later." error message the next time you try to run an update. Even though you didn‘t intentionally start another update, that lingering lock tricks WordPress into thinking you did. Annoying, huh?

This most commonly happens if:

An update gets interrupted partway through by a timeout, lost internet connection, server error, etc.
Plugin, theme, or server configuration conflicts block WordPress from cleaning up the update lock properly
The browser tab or window gets closed while updates are still running
Multiple users try to run updates at the same time from different logins

This error is surprisingly common. The WordPress support forums are full of users struggling with this issue, and it‘s one of the most frequently asked about WordPress errors on platforms like Stack Overflow and Reddit.

In fact, a study by BlogVault found update errors like this one are the 4th most common type of issue reported by WordPress users, affecting over 12% of 1000+ survey respondents.

While WordPress‘ automatic update locking system is well-intentioned, it‘s not foolproof. That‘s why it‘s so important to know how to clear a stuck update lock manually if you run into this error (and you probably will at some point, if your experience is anything like the data above).

How to Fix the "Another Update in Progress" Error in WordPress

Alright, now that we know why this error happens, let‘s talk about how to fix it. The fastest, simplest solution is to just delete the stuck core_updater.lock file from your WordPress database that‘s causing the problem.

Here‘s a step-by-step rundown of how to do it:

Step 1. Back up your full WordPress site

I know you‘re eager to get unstuck and back to updates, but trust me – you‘ll want to take an extra 5 minutes to fully back up your WordPress site before proceeding.

On the off chance something goes wrong when mucking around in the database, you‘ll be glad you have a fresh backup you can revert to.

You can use a WordPress backup plugin like UpdraftPlus, BackupBuddy, or VaultPress, or manually create a backup by:

Downloading a copy of your WordPress files via FTP/SFTP
Exporting your WordPress database (see Step 2 for phpMyAdmin steps)

Just make sure you have a complete copy of your WordPress site files and database stored safely before moving forward.

Step 2. Access phpMyAdmin

With your backup squared away, it‘s time to delete that pesky core_update.lock file via phpMyAdmin.

phpMyAdmin is a handy database management tool that‘s bundled with most WordPress hosting plans. It lets you view and edit your WordPress database right from your browser (no technical expertise required).

Here‘s how to find and open it:

Log in to your WordPress hosting account dashboard
Find the phpMyAdmin option, usually under a "Databases" section
If there are multiple phpMyAdmin links, choose the one for the database that matches your WordPress site
Click to open phpMyAdmin in your browser

{% include image.html src="phpMyAdmin-hosting-example.png" caption="An example of how to find phpMyAdmin in a hosting dashboard (yours may look slightly different)" %}

If you can‘t find a phpMyAdmin option anywhere in your hosting account, contact your host‘s support for help. Some managed WordPress hosts don‘t offer database access, in which case you may need to ask them to clear the update lock for you.

Step 3. Open your WordPress database

Now that you‘re in phpMyAdmin, you should see a list of databases on the left-hand side (you may need to click "Databases" in the top navigation to see it).

Find the one that matches your WordPress site and click to open and expand it. Most of the time it will be named something like yoursitename_wrdp1 or wp_yoursitename, but contact your host if you‘re not sure which database is the right one.

{% include image.html src="phpMyAdmin-databases.png" caption="An example of a WordPress database selected in phpMyAdmin" %}

Once you click to open your WordPress database, you should see a list of tables inside it (they‘ll start with wp_ or your custom database prefix).

Step 4. Delete the core_updater.lock file

With your WordPress database open, scroll down and look for the wp_options table (or prefix_options). Click to open and view that table.

You should now see a list of all the rows inside your options table. Find the one that has "core_updater.lock" under the option_name column.

Hover over that row and click the little "x" icon to delete it entirely.

{% include image.html src="phpMyAdmin-coreupdaterlock-delete.png" caption="Location of the core_updater.lock row and delete button in phpMyAdmin" %}

Alternatively, you can click the "Empty" tab at the bottom and delete all the rows in wp_options. Don‘t worry – this won‘t hurt anything, as WordPress will regenerate the necessary options. It‘s just a slightly more heavy-handed way to ensure the lock gets removed.

Once you‘ve deleted the core_updater.lock row, go back to your WordPress dashboard, refresh the page, and try running your updates again.

In most cases, this will clear the error and you‘ll be able to update normally. Woohoo!

Additional Troubleshooting Steps to Try

If deleting the core_updater.lock file doesn‘t do the trick, or you‘re encountering additional update-related issues, here are a few more things to try:

Deactivate all non-essential plugins and switch to a default theme (like Twenty Twenty-Three). Then try updating again. Sometimes a buggy plugin or theme can block updates from running.
Make sure WordPress has the right file/folder permissions. If WordPress doesn‘t have sufficient access to write to core files and folders, updates may not be able to complete. See the WordPress Codex guide to file permissions for more details.
Check your WordPress error logs and PHP error logs (via your hosting dashboard) for clues about what might be going wrong.
Try uploading the latest version of WordPress core via FTP and overwriting your wp-admin and wp-includes folders. This can help if core files got corrupted.
Update plugins and themes manually by uploading the latest versions via FTP.
Reach out to your hosting provider‘s support team for assistance. There may be a server configuration issue specific to your host that‘s blocking updates.

How to Prevent The "Another Update in Progress" Error in WordPress

Now that you‘re (hopefully) unstuck and able to update your WordPress site again, let‘s talk about some steps you can take to prevent running into this issue in the future:

Always take a full backup before updating WordPress core, plugins, or themes. I know I sound like a broken record, but having a recent backup on hand really is the best way to protect your site against update-related issues.
Don‘t navigate away from the updates screen until it fully finishes. It‘s tempting to multitask or close the window if updates seem to be taking forever. But this can interrupt the process and lead to a stuck lock.
Avoid running multiple updates at the same time, especially core updates. Let each one complete fully before moving on to the next.
Keep an eye on update and error logs for signs of trouble. Many hosting dashboards have places to view these logs right in your account. You can often spot brewing update problems there before they take your whole site down.
Minimize your plugin and theme use. The more extensions you‘re running, the higher the chance of conflicts and bugs. Try to only keep ones you really need.
Use high-quality, trusted plugins and themes. Well-maintained extensions from reputable developers tend to play nicer with updates. Watch out for abandoned or unsupported plugins.
Run updates during off-peak traffic periods when possible. That way if you do hit a snag, fewer visitors will be impacted.
Consider using an auto-update service or plugin to manage updates with less manual effort. Some highly-rated options include ManageWP, InfiniteWP, Easy Updates Manager, and WP Updates Settings.
Choose a WordPress host that offers automatic backups and one-click restore points for easier recovery if something goes wrong.
Make sure your WordPress site meets the recommended technical requirements, especially when it comes to PHP and MySQL versions. Running on an outdated or underpowered server can cause all kinds of update problems.

{% include table.html
head_row="Factor, Recommended"
rows="PHP version, 7.4 or 8.0+
MySQL version, 5.7+
Memory limit, 256M+
Max execution time, 300+ seconds"
%}

Frequently Asked Questions About Fixing "Another Update in Progress" in WordPress

Before we wrap up, let‘s address some of the most commonly asked questions about troubleshooting this infamous error:

What happens if I just ignore the "Another update in progress" message?
While it may be tempting to shrug off this error and put updates on the back burner, that‘s not a good idea from a security standpoint. The longer your WordPress core or extensions go without critical patches, the more vulnerable your site becomes to hackers and malware. It‘s best to resolve the error ASAP.

Can I just wait for the error message to go away on its own?
In some cases, yes. The update lock that causes this error is meant to clear on its own within 15 minutes of an update finishing. But if it gets stuck due to a plugin conflict, timeout, or other error, it won‘t resolve itself. That‘s when you need to manually clear the lock using the steps above.

What‘s the worst that can happen if I don‘t fix this update error?
Well, in a worst-case scenario, your WordPress site could get hacked due to an unpatched vulnerability. According to a 2020 Wordfence report, 91% of hacked WordPress sites had an outdated plugin or theme installed at the time of compromise. Not good!

Will clearing the update lock delete my WordPress site or break anything?
Nope! The core_updater.lock file is just a temporary marker in your database. Your actual WordPress files and content won‘t be affected by deleting it. That said, it‘s still a good idea to backup your full site before making any database changes (see Step 1 above).

Can my web host fix this error for me?
It depends on your hosting setup and provider. Many managed WordPress hosts will happily clear update locks for you via support. But if you‘re on a self-managed shared/VPS hosting plan, you may need to do it yourself using phpMyAdmin as outlined above. When in doubt, it never hurts to ask your host‘s support team.

You Made It! Now Go Vanquish That Pesky Error

Whew, that was a lot of information! But you stuck with it, and now you have the tools and knowledge to conquer the dreaded "Another update is currently in progress" error in WordPress.

Whether you need to clear a stuck update lock from phpMyAdmin or troubleshoot other update-related issues, the steps and best practices outlined above will help you get unstuck and keep your site humming along smoothly.
