How To Clear Your Cache In WordPress

We’re going to provide you with tutorials showing How To Clear Your Cache In WordPress using plugins, how to remove cached information from your web hosting, and how to remove browsing data from your web browser.

You can easily clear the cache in WordPress through the Cpanel of any web hosting services provider. One of the easiest platforms to manage hosting panels is Hostinger Hpanel and if you are finding the best one then Hostgator Web Hosting is best to use.

Caching in WordPress – what is it?

WordPress caching improves the performance of the website. If the site receives an excessive amount of traffic, you should install any caching plugins like W3 Cache or WP Super Cache to enable WordPress caching.

You can also use WP Rocket which is one of the best premium cache plugins for WordPress

Using WordPress caching to speed up new requests is when an application receives repeated requests from different clients, reusing previously generated data (or requests such as database queries) to speed up the process.

Types of caching protocol

Depending on the client-server model, there are two primary types of caching protocols. The protocols are as follows:

  • The first protocol is a client-side caching protocol
  • The second protocol is a server-side caching protocol

The Client-Side caching protocol

Unlike text-based websites, static websites contain many non-text files, such as images, CSS files, and Javascript files. Your browser automatically downloads them when you visit those pages.

In other words, your computer can serve that data out of the local cache, i.e. the cached data that is stored on your hard drive.

Because of this, it is recommended that you clean the cache of your browser every now and then since it can save a lot of space.

The process where the client’s computer (or client’s end) uses the cached data from the server is known as client-side caching, which is used by every modern website and supported by every browser.

Client-side caching reduces server overhead (it prevents data from being downloaded over and over again) while saving a lot of time for the server.

How to clean client-side cache ( Browser cache)

Clearing the browser cache is a very straightforward process. If you are using Chrome, you simply need to go the Setting-> Security And Privacy-> Clear Browsing Data

You can also simply click on the three dots at the right top corner and go to More Tools-> Clear browsing data

The Server-Side caching protocol

Client-side caching and server-side caching are similar concepts. It nonetheless stores data from the cached version of a website on a server.

The server cache can store data from multiple databases, making it an excellent choice for high-traffic websites. WordPress cache functions are handled by server-side caching, which includes various caching protocols. Listed below are a few of them:

  • The Page caching protocol
  • The Database query caching protocol
  • The Object-based caching protocol
  • The Opcode caching protocol

Purge From Cache – What Does It Mean?

A purge of the cache means, basically, re-caching previously cached data. Essentially, the old ones are removed and new ones are created or regenerated. These procedures are usually conducted based on a variety of protocols, including:

  • Whenever a comment is posted
  • Whenever a new post is published
  • When an older post is updated

You can explain the same principle with three different phrases: clear your cache, delete your data, and purge your registry.

With this option, you are deleting any saved information your browser or server has made available about your WordPress site, including cached images, files, and pages. Your browser will pull new information from the website server the next time you load your website.

If you are using a saved login with your WordPress account, you will have to re-enter that again. Please make sure to write that down somewhere safe so you can re-enter it later! 

It’s likely that you will see a difference in page loading speed after purging all cache. When your caching solution caches a new, optimized version of your website, your page speed should return to normal. (And we mean slower speed, not faster speed.)

What You Can Gain by Clearing Your Cache

You might find it useful to clear your WordPress cache when you’re making changes to your WordPress website and want to see the changes immediately. Whenever you visit a page, the WordPress cache displays your old content in the form of old data. 

When you make changes to your site, you will want to clear the cache to ensure the site can display the new information and content that you have added.

Most of the time, clearing your cache helps if you’re making changes to your site’s visuals and the changes aren’t being reflected when you refresh or reload it.

Depending on what you’re trying to fix, clearing your cache can also be useful for troubleshooting. Essentially, clearing your cache means that you are removing your website’s temporary storage. It will make your website administration easier in the long run if you learn how to do this.

A Warning Regarding the immediate after-effects of clearing the cache 

  • When you log out of a site that you have an account with, most of your browsing history will be wiped 
  • On some websites, you may have to input your transaction details again
  • The speed at which pages load will change

WordPress Cache Cleanup: How Much Investment is Needed

Your next question might be, what will it take for you to completely erase your WordPress cache? Does the task seem very time-consuming?

What skills will you need in order to launch your site? Will you have to know the code or go into the site’s root files? Will effective cache clearing require you to pay a fee?

Beginners might not understand how simple it is to clear the cache of the site using a WordPress plugin. If your hosting provider offers a caching solution that allows you to access your site’s cache without the need for a cache plugin, you might not even need one.

The WordPress dashboard will usually allow you to use a caching tool when you install WordPress through your hosting provider.

As an alternative, you can make use of a caching plugin that we will discuss later in this guide. Finally, remember that you can configure your cache in your FTP file through FileZilla if you’re up for it.

But you should take the utmost care when using this method and we recommend you leave it as a last resort only if all other options have failed.

  • When You Have a CDN, how to Clear the Cache using it

WordPress websites can benefit from an extra level of caching through a content delivery network (CDN). An Internet content delivery network (CDN) sends a cached version of your website from one of its far-flung data centers to website visitors in their own locale.

Therefore, you are not only benefiting from rapidly delivering cached content to visitors, but you are also reducing the physical distance between the server and them. You will be amazed at how fast your site will load.

In order to clear the cache on your CDN, you will need to log into your third-party CDN platform. There will be an option easily available to clear the cache

  • When You Have a WordPress Firewall, how to Clear the Cache using it

Essentially, WordPress firewalls are reverse proxy servers, because they review and filter traffic before it reaches your website. There is one significant difference, however, in that the proxy is intended for the enhancement of website performance and the firewall is meant for security.

Several tools are available for implementing firewalls, but not all tools let you remove the WordPress cache. There are, however, several WordPress firewall plugins that allow content caching, including Sucuri Security and Cloudflare.

  • With Sucuri Security, you can clear WP cache

In your WordPress admin dashboard, select the Sucuri > WAF menu item if you are using the WP Sucuri plugin. Select the Clear Cache button under the Clear Cache tab.
