How to Clear WordPress Cache

How to Clear WordPress Cache

Due to their dynamic nature, most websites go through a process of constant change and development. This includes occasional modifications and improvements of the website design itself, the addition of some new elements, as well as frequent content updates. Because of all these, situations may occur where you may not be able to see some of these changes, even after reloading the page.

If a similar situation happens to you, the reason for this may be the WordPress cache files that are out of date. Most commonly, the solution for this lies in clearing your WordPress cache. In this article, we will talk a bit about how caching works, why you should clear your cache, as well as list different ways to do it on your WordPress site, so stick around:

What is Cache and Why It Is Useful

When a visitor comes to your website, their browser will store all the static content (like JavaScript, CSS, HTML, and images) as cache files. So, the next time they choose to visit your web page again, the stored data will ensure that it loads faster, as some of your website’s content is already fully downloaded. Therefore, the main purpose of caching is to boost your website’s speed and enhance the overall user experience of your visitors.

Why You Should Clear Your WordPress Cache

That being said, caching can sometimes cause some unexpected issues. For example, instead of showing new content, it can still show an old, cached copy of your WordPress site. This means that not only your visitors won’t see any changes right away, but also the webmasters won’t be able to preview the changes they made on the website. You can run into this issue if you make some changes to your website design or content, or if you recently updated your themes and/or plugins. In all these cases, clearing your WordPress cache should do the trick.

There are many caching plugins and firewall solutions that provide the option of optimizing your website’s speed and performance using cache, and a lot of them include the option of clearing cache on your WordPress site. This time around, we will show you how to clear cache using some of the most popular plugins in this category. In addition, we will explain how to do it in your website browser and using your hosting service options as well.

With that said, here are some of the best ways in which you can clear your WordPress cache:

Clearing Cache Using Your WordPress Hosting

To do an in-depth caching of your WordPress site, we suggest that you clear the cache on your hosting server as well. If you perform caching on your server, you will also be able to take care of your PHP and MySQL files, object caching, etc.

Different WordPress hosts provide different ways to clear your cache. If you use Bluehost, for example, you will be able to easily clear your cache from the WordPress admin area by clicking on the Caching button in your admin toolbar and selecting Purge All.

If SiteGround is your hosting provider, you can clear your cache using their cPanel. Alternatively, you can do this directly from your WordPress dashboard by installing a plugin created by SiteGround called SG Optimizer. After installing and activating the plugin, a new menu item will appear in your admin toolbar called Purge SG Cache. Just click on this button and you’re all set.

To clear the cache on WP Engine, you will also be able to access this option from your admin area. Simply click on the WP Engine menu item and click the Purge All Caches button in General settings.

No matter if you’re using one of the above-mentioned services or another WordPress host entirely, we recommend that you contact your hosting provider directly if you have any uncertainties about clearing cache files from your server. Even if they don’t provide you with the ability to do it yourself, they will most likely be able to do it in your stead.

Clearing Cache Using a Firewall Plugin

If you use a WordPress firewall plugin, it may also come with the option to clear the cache on your site.

Sucuri Security is a good example of a plugin that allows users to clear the cache from their admin area. If you use this plugin, head to Sucuri Security >> Firewall (WAF) in your WordPress admin and hit the Clear Cache button located in the tab with the same name:

Firewall Clear Cache


While caching is a great way to boost your site’s speed and overall performance, sometimes you may need to clear your cache to ensure that you and your visitors can see the latest updates to your content as well as other changes you made to your website.

We recommend that you clear the cache in your browser first and see if that fixes your problem. If not, there are many great caching plugins around that will help you purge your cached files quickly and effortlessly. Finally, for more thorough results, you can also clear the cache on your server using some of the available options that come with your hosting.
