Recently, one of our readers asked us how to clear 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’ll often hear.
In this article, we will show you how to properly clear the cache in WordPress. We’ll cover browser cache, web hosting cache, and top WordPress caching plugins in this guide.
What is Cache and When Do You Need to Clear Cache?
Caching solutions store a static version of your website. This allows WordPress to skip running the heavier PHP scripts and improve your website speed.
There are many different type of caching solutions available. The most popular ones are WordPress caching plugins like WP Rocket and WP Super Cache.
These plugins offer an easy to use interface for controlling what to cache, when to expire cached content, and cleaning up cache on demand.
Managed WordPress hosting providers like WP Engine also run their own caching solutions, so that you don’t have to install a caching plugin.
If you are using a CDN service like MaxCDN, then they would also serve cached copies of static content.
If you’re using a web application firewall like Sucuri or CloudFlare to improve your WordPress security, then they also have their own cache to speed up your site and reduce downtime.
Lastly, most modern web browsers will also store cached versions of pages on your computer.
The purpose of caching is to speed up the website and improve overall user experience. However, sometimes this causes you to not see the changes you make right away which can be frustrating. In that case, you will need to clear caches to see your changes live.
Having said that, let’s take a look at how to clear your cache in WordPress.
Step 1: Clear Your Browser Cache
However, sometimes web browsers may fail to realize that a web page has changed. Instead of fetching a fresh copy, they may still reload the page from the cached version stored on your computer.
Here is how you will clean your browser cache in Google Chrome. First, you need to click on the menu icon and then select More Tools » Clear Browsing Data.
This will bring up a popup where you can select the content you want to remove. Make sure that cached images and files option is checked and then click on the ‘Clear browsing data’ button.
You have successfully cleared your browser cache, and you can now try visiting your website. For more details, see our guide on how to clear cache in all major browsers.
