How To Clear The Cache In WordPress

We use caching on most websites to help the user experience.

Caching saves a copy of images, css etc so it doesn't need to be fetched every time.

It's great when everything is running normally, but can be annoying when you're trying to change the design.

How to clear the WordPress Cache

For someone who works in IT, the default first step when something isn't working is "have you turned it off and on again?"

For those of us in web design and development, the default first step if things aren't working is "have you cleared the cache?"

I'm going to cover the following in this tutorial. Click the appropriate link to skip to the part that's relevant for your setup.

After clearing the cache in the plugin or server, go to the page you're working on and force refresh.

How to force refresh your browser

F5 reloads a web page in Windows, but to force refresh the browser, use:

  • Windows: CTRL + F5
  • Mac: ⌘ R
  • Linux: F5

This will clear the cache and refresh the webpage. If you don't have a WordPress caching plugin or server-side caching, this may be all you need to do.
