To speed up WordPress and make it load as fast as possible, you have to install one of the popular caching plugins, such as W3 Total Cache, or WP Super Cache. Both plugins work well, but sometimes, you need to correct some caching errors that can happen, and that’s normal and not a dangerous situation.
If you think that your site is partially broken, or something wrong is going to the display, such as an outdated homepage, then, you need to clear the cache, and it’s an easy task to do. In this post, I’ll show a step-by-step tutorial on how to clear your WordPress cache manually.
Clear WordPress cache on WP Super Cache
The first thing that you need is to log into the WordPress admin area. Then, click “Settings” and next, “WP Super Cache” from the left menu, as the next screenshot.
Now, in the plugin control panel, you need to click on “Content”, as in the following example:
The final step will be to click the “Delete Cache” button, and the plugin will delete the site cache. Of course, it will recreate a new cache that’s updated, and that will solve your caching errors in the majority of cases.
If you still see the old cache from your browser, make sure to delete it, then, check the page again, and you will see the new cached pages.
W3 Total Cache
This is the second most popular WordPress caching plugin used by millions of people. It needs some detailed settings and configuration, and that’s what can cause caching errors, sometimes. Anyway, to delete the blog cache if you’re using this plugin, click the “Performance” link, then, you get the plugin dashboard.
From there, you can click on “Empty All Caches”, as shown in the next screenshot.
The plugin lets you choose which cache you want to delete. If you want to delete a particle cache, you get the appropriate options, depending on your server configuration. As you can see in the example below, there is an option to delete the Memcached cache bounce when the server is configured with it.
You can also, use the top WordPress admin area menu to delete the site cache. All you have to do is click “Performance” and then “Empty All Caches”, and the job is done easily.
You can get your site cache in simple clicks, but remember that you can fix problems if you spend some minutes looking into the settings and configurations of the plugin. If you’re using WP Super Cache, for example, make sure that you check the options that regenerate the cache, when a new post or page is created or updated.
Also, you can exclude your site’s home page from the cache if you see problems there. You can just scroll down on your plugin dashboard, then, locate “Accepted Filenames & Rejected URIs”, and you will be able to exclude the front page and the home page from the cache. That way, you will avoid lots of issues with caching.
For W3 Total Cache, be careful with the Minify section. It can cause lots of display errors and problems. Lots of sites that have poor configurations with that plugin will look broken, and you can avoid that by disabling the “minify” option in your cache. That’s just an example of how to solve many of the problems that can be caused by the site’s cache.
