How to Flush the Caches of Your WordPress Plugins

At one point, you may have published an article or made a CSS update only to load your homepage and not find it there. Chances are the problem is cache.

If you have a large website, with huge traffic, caching can be a handy tool to optimize page load time.

In this article, we will show you how to clear the WordPress cache.

Cache makes a website load faster which offers tons of benefits when loading scripts and images. It is defined as a location in a browser where web pages are stored in memory for easier retrieval at a later time.

Ideally, browsers and web servers rely on HTML instructions to create pages from items stored in various locations in a website. If cache doesn’t exist, it means that you have to build these pages every time the server asks for one. To simplify the process, cache stores these pages in a separate memory to enable the user to use it again.

A website built on WordPress has three types of cache:

  • Browser: it is located on your machine or device and stores all your website information that can be used over and over again. It acts as a memory storage when you need a certain webpage.
  • Cache Plugin: The plugin is made to submit already created web pages to speed up the time it takes to create a new page.
  • Server Cache: With the help of a cache plugins, the host can provide storage from premade web pages to make it easy for a visitor to load them thus reducing the load time.

In this tutorial, we will look at the most common areas to start with when clearing cache on WordPress.

Step 1: Clearing Cache on Your Browser

First, you need to clear your web browser’s cache. It is common for web browsers to store static pages like images, JavaScript, stylesheets, and other pages to make your website faster.

Here is how to clean your browser cache.

Go to your main menu, select More Tools >Clear Browsing Data.

You should see a popup page where you can choose the information you want to remove. Ensure that all the cached images and files box is checked then go ahead and hit the “Clear browsing data” button.

Now you have successfully cleared cache on your browser. If there are no changes on your browser, you can proceed to the next step.

Step 2: Clearing Cache on WordPress Caching Plugin

If you have a problem with your browsers, you should try to clear data on cache plugins. For WordPress websites, you need to clear plugin cache. You can do this from the setting page of the plugin.

If you don’t find the setting, you can ask the admin to clear it for you. They may ask you to perform several other cache options first.
