You may also experience issues with logging into WordPress. It’s good to know about these possible errors so you can be prepared and able to fix them quickly.

Sometimes it can happen that W3 Total Cache won’t cache all resources. If this happens, you can rely on the debug tool to see what is and what isn’t cached. After you completed all the tests and you are still experiencing issues with the plugin, you might want to consider opting for a different caching plugin.
W3 Total Cache errors : 404
Another common issue that may arise is a 404 error, especially since recent WordPress updates. These errors usually occur in Google Search Console or GT Metrix. Free plugins have disadvantages and in this case, as well, can cause problems. When you choose to use free plugins keep in mind that they may not always be maintained and compatible with the latest WordPress updates. This can cause issues.
The easiest fix is to disable caching of 404 pages or perform a fresh installation. What you can also do is investigate the source of the 404 error, you might be lucky to be able to fix the error without having to reinstall the entire plugin. However, these fixes won’t work in all cases, so you should also consider switching to a fully compatible, up-to-date plugin to improve the loading time of your WordPress page.
W3 Total Cache errors : 500 or wp-admin error notification
With the page caching option enabled and using WordPress in network mode can raise further problems, such as the error 500 or the wp-admin error notification. W3 Total Cache is known to cause numerous 500 errors, while the extent of the problem may depend on the hosting service’s use of Varnish. In such cases, the most effective solution you can opt for is modifying your .htaccess file. You can also try the “combine only” option on the CSS tab of the plugin’s settings and then choose “auto” on the Minify tab settings. This fix is known to be effective as well in some cases.

In case you encounter this error, you’ll have to remove the plugin entirely. Before reinstalling it, make sure that any remaining files are also deleted.

In case you cannot solve the issue, then our advice is to switch to a premium cache plugin such as Swift Performance AI.
