How to Clear WordPress Cache On Your Site – Kinsta

WordPress clear cache

Website performance depends on many aspects of your site: design, the platform being used, and how you optimize its various elements. Site caching is one of the most crucial ways to improve site performance, and for a good reason. Almost all WordPress sites have caching enabled to store resources efficiently and speed up the site.

Sometimes, you may want to clear this cache. We’ll show you exactly that, teaching you how to clear WordPress cache using various methods.

Kinsta users have an advantage when it comes to caching. All caching is handled server-side by Kinsta, which includes full-page and object caching. This means that Kinsta users don’t have to clear the WordPress cache on their own. Sure, there’s an option for a manual cache, but there’s no need for third-party caching plugins or automated caching configuration—it’s already set up for you. The full-page cache is set to one hour by default, but Kinsta can customize that for you if needed.

But what if you don’t use Kinsta for some of your websites? Don’t worry, because various plugins offer caching tools to automate the process and ensure your site runs at top speeds.

In this article, we’ll talk about the basics of caching, explain how to clear WordPress cache through the MyKinsta dashboard, and with some of the most popular WordPress caching plugins.

What’s Caching?

Simply put, caching minimizes the amount of work required to produce a webpage for viewing.

WordPress cache achieves this more efficient environment by storing static versions of your webpages. These copies are held in the WordPress or website cache until the cache expires, content is changed, or the cache receives an order to purge.

Think of the cache as a storage area for several snapshots of your website’s history. It delivers these snapshots to the end-user instead of forcing the server to compile and deliver all site files every time they want to see a webpage.

An Example of What Happens When a Webpage Loads Without Caching:

  1. Someone comes to your website via a search engine or outside source like social media. They land on one of your webpages, such as the homepage or a product page.
  2. An HTTPS request is put into effect, telling your web server to compile all files to deliver that webpage. Each element (image, script, and file) that goes into that page takes time for the server to compile.
  3. After all site files and elements are requested and loaded, the user sees the entire webpage.

Again, it depends on the file sizes and the number of files on that page, but it’s a lot of work for your server to piece together the right components of a webpage every time someone wants to view it.

An Example of What Happens When a Webpage Loads with Caching in Place:

  1. Someone comes to your website and ends up on an individual webpage.
  2. An HTTPS request gets sent to your server to compile files and deliver the webpage in full form.
  3. Caching is enabled,
