Recently, one of our readers asked us how to clear the cache in WordPress.
Your web browser, hosting server, and caching plugins can all serve cached content, which can make it difficult for you to see the changes you made to your website right away.
Clearing your WordPress cache is also the first troubleshooting advice that you will often hear.
In this article, we will show you how to properly clear the cache in WordPress. We will cover browser cache, web hosting cache, and the top WordPress caching plugins in this guide.
What Is Caching in WordPress?
Caching solutions will store static versions of your website in a cache. This allows WordPress to skip running heavier PHP scripts every time your site loads.
The caching process helps to improve WordPress speed and performance and the overall user experience.
Here’s an example of what the caching process looks like:
These plugins give you control over which files and media are cached when the cache expires, when the cache is cleaned up, and more.
Depending on your hosting provider, you might already have WordPress caching built in. For example, managed WordPress hosting companies like WP Engine run their own caching solutions.
Finally, most modern web browsers will also store cached versions of pages on your web browser.
Why Clear Your WordPress Website Cache?
Sometimes the cache won’t realize that changes have been made to your WordPress website. Instead of loading the new version of your site, you will be stuck seeing an old version.
This will prevent both you and your visitors from seeing any updates you have made.
Clearing your WordPress cache ensures the most recent version of your website will always be live.
With that said, let’s take a look at how to clear your cache in WordPress. Simply use the quick links below to jump straight to the method you want to use:

Method 1: Clear Your Web Browser Cache
But sometimes, web browsers may fail to realize a web page has changed. Instead of fetching a fresh copy, they will load the page from the cached version stored in your browser.

This brings up a popup where you can select the content you want to remove from the cache.
Make sure the ‘Cached images and file’ box is checked, then click the ‘Clear browsing data’ button.
Now, you have successfully cleared your browser cache. You can visit your WordPress blog to see if it’s loading the new version of your site.
