Object caching is a type of cache that caches database query results for web pages after the results are loaded. This way, on each subsequent page load, queries are quickly served from the cache.

This prevents having to burden the database with the same query every page load, saving server resources and speeding up page load times.

Popular object caching programs include Memcached and Redis. There are also WordPress plugins that provide object caching, such as W3 Total Cache. Any of these could be the root cause of the “database is already up to date” error.

This happens when files that indicate WordPress are up-to-date are cached. This file is checked when a new update is available, and since it still says WordPress is up to date, the error message appears because it thinks everything has been updated.

How to fix “The database is already up to date” error


Now that you know why you get the “database is already up to date” error, how do you fix it? There are multiple ways to fix this problem, and you can try each one until you find a solution that works.

Clear the cache of your WordPress site and server
Rename the object-cache.php file
Disable all plugins
Last resort: contact your host or restart your server
Clear the cache of your WordPress site and server
Clearing your site’s cache might fix the problem, as it should clear the cache files that indicate your WordPress database is already up to date. If that doesn’t work, try clearing the server’s cache.

These steps vary depending on the plugin and host you’re using, so see their documentation for details on how to do this.

Keep in mind that clearing your site’s and server’s cache can cause temporary performance issues. However, when your website pages are cached again, this problem will resolve itself.

Clear cache with WP-CLI
If your host supports it (most do), you can use WP-CLI to clear the cache.

Step 1: Connect to your site via SSH. Depending on your host, this step may vary.

Step 2: Next, enter the command below, but be sure to update “path/to/your-site” with your site’s actual path:

cd ~/path/to/your-site
Step 3: Now, refresh your site’s cache by typing:

Clear cache with SSH

If you don’t want to use WP-CLI, you can flush your site’s cache using SSH. The commands you should use will vary depending on the type of object caching system you are using.

Step 1: After connecting to the server via SSH from the client or host’s dashboard, if you have Redis installed, you can use the following command:

redis-cli flushall async
Alternatively, if you have Memcached installed, use the following command to start the process instead:

telnet localhost 11211
Remember, if you don’t use that port, you may need to update “localhost 11211”.

It’s also important to note if the server hosting your site doesn’t support memcached. As we said, you can use the Redis plugin instead.

Step 2: If you are using Memcached, there are a few more steps. Next you need to enter the following command:

Step 3: The last step is to exit by simply typing the word into the SSH client, like in this example:

Rename the object-cache.php file
If you’ve tried clearing your site and server’s cache without success, you can try renaming the object-cache.php file.

It’s also especially useful if you can’t clear your site’s cache due to the “database is already up-to-date” error that you can’t access the WordPress admin dashboard.

If you find yourself in this situation, you should be able to revisit your site after renaming the file.

Step 1: You need to access the object-cache.php file to start solving the “Database is already up to date” error. You can choose to do this via SSH, SFTP, or via your host’s dashboard.

Then, click Sites in the menu, select your site from the list, and click the Information tab.

Here are the details you need to record on this tab, or if you host your WordPress site elsewhere:

IP address
username
password
port

Step 2: Log in to your server via an FTP client (such as FileZilla in the example below) using the SFTP credentials you noted down. Add your details at the top of the window and click Quick Connect.

Step 3: Below the login field, there is an area that displays a message directly below.

Once you see the “Connected to” message, then your server’s IP address, then “‘/’ Successful directory listing”, it means you are connected and ready to go.

Navigate to your website’s /wp-content/ folder and find the object-cache.php file there.

Step 4: Rename the file to whatever you want, appending something like “-old” to the end of the existing name can be helpful. This makes it easier to find and remember the contents of that file later.

In FileZilla, click on the file. Then, right-click it and select Rename in the menu that appears. If hidden files are not showing, follow this tutorial to fix it.

Type the name you want and press Return or Enter on your keyboard.

Step 5: Go to your site and log in. Then, clear your site’s cache with whatever caching plugin you’re using.

Step 6: Go back to your FTP client and check that the file has been recreated on your server.

Disable all plugins
If nothing has worked so far, try disabling all plugins. For example, this can resolve the “database is already up-to-date” error in cases where you use two cache plugins that handle different types of caches. Maybe you accidentally overlapped the function that caused the error.

Or maybe you forgot that the plugin you were using had additional functionality for caching or similar and you forgot about it.

In either case, if you don’t have access to the admin dashboard, you can disable all plugins using SFTP. Here’s how to do it.

Step 1: Similar to the previous suggestion to rename the object-cache.php file, open your preferred FTP client and connect to your server.

Find the /wp-content/plugins/ folder and rename it. Similar to renaming the object-cache.php file, you can name the plugins folder whatever you want, but appending something to the end can help you avoid confusion later.

Step 2: Log back into the Admin Dashboard to make sure you can and don’t get the “Database is already up to date” error again. If you are there, rename the plugins folder to its original name and refresh the admin dashboard.

Step 3: Clear your site and server’s cache as previously described. Then in your site’s admin dashboard, go to Plugins > Installed Plugins.

Reactivate each plugin one by one until the problem reappears. When it happened, you found the plugin that was causing the problem.

Step 4: If you still have access by clicking the “Remove” link below the plugin’s name in the list, delete the problematic plugin in the admin dashboard.

Otherwise, use SFTP again and rename the plugins folder again.

Step 5: Once done, rename the plugin folder to its original name again. Then, refresh your browser and remove the problem plug-in, as described in step 4 above.

Step 6: Clear your site and server’s cache again. At this point, the “database is already up to date” error should be resolved.

Last resort: contact your host or restart your server
If you reach this point and nothing else works, try restarting your server. But before that, keep in mind that this is an absolute last resort as it means your website is temporarily unavailable.

No one will be able to access your site, so if you need to restart your server, try to do it during the day or night when traffic is lowest.

Each hosting provider has different steps for restarting the server, so be sure to check their documentation for details on how to do it.

Before restarting the server, you should try contacting your host first to see if they can fix the problem. Be sure to let them know all the steps you’ve taken so far to try and fix the “database is already up to date” error.

Summary


All in all, it is very important to keep WordPress up to date as new updates come with useful features and important bug fixes. Not being able to update your website can be annoying, and not having an update loop can be one reason.

The problem arises mainly because of conflicts with object caching. While caching is critical to improving website performance, it can create problems on your website if not handled properly.

In this article, we discussed the reasons and different ways to fix the WordPress loop without updating. We’ve seen how object caching can trigger horrific bugs that can even lock you out of an admin dashboard. Also, we have a detailed look at all possible solutions to the problem.

All in all, the first thing you can do is clear your website’s cache. If this doesn’t solve the problem, you need to manually rename the object-cache.php file. If the problem persists, a good idea is to check for conflicts between plugins/themes. In most cases, after this, the update not needed error will go away, but if that’s not the case, restarting PHP or your server might be the solution. Finally, if nothing works, you should contact your hosting provider for technical support and help you fix the “no update needed” loop.
