Performing tasks like WordPress clear cache regularly is important to help remove any unnecessary data stored on your site and improve the speed and performance of your WordPress website.

If you’ve ever made changes to your WordPress website and found that they don’t show up right away, it may be because of caching.

Caching saves a copy of your site’s content in different places, like your web browser, hosting server, or caching plugins.

Clearing the WordPress cache is often the first troubleshooting step recommended to fix this issue, and in this article, we’ll show you how to properly clear the WordPress cache.

What is WordPress cache?

It refers to the temporary storage of frequently accessed data. For instance images, scripts, and other website content, that is stored on your website or browser in order to speed up page loading times.

When a website is visited, the cached data is used instead of fetching the data again from the server, resulting in faster page load times.

Caching is an important feature for optimizing WordPress site speed and performance, but it can also sometimes cause issues if the cache needs to be cleared or updated.

How to cache in WordPress?

There are different ways for WordPress caching, but the most common method is to use a WordPress caching plugin, like WP Rocket or WP Super Cache plugin.

These caching plugins allow you to control what content is cached, how long it’s cached, and when it’s cleared.

Your hosting provider may also offer built-in caching solutions. For example, managed WordPress hosting companies like WP Engine have their own caching system, while hosts like Bluehost and SiteGround provide caching features to their users.

If you use a web application firewall, such as Sucuri or Cloudflare, to enhance your WordPress website’s security, it may also include a caching system to speed up your site and reduce downtime.

In addition, modern web browsers automatically store cached versions or cache files of web pages, which means that if you’ve recently visited a website, your browser may display a cached version of the page instead of loading the updated version.

Why is it important to clear cache in WordPress?

Simply, because visitors can see the most up-to-date version of your website.

When you make changes to your site, like updating content or changing its design, the old version of the page may still be stored in the cache.

If a visitor tries to access your site, they may see the old version instead of the updated one, which can be frustrating for them and can impact your website’s credibility.

Clearing your website cache can also help improve your website’s performance. Over time, the cache can become cluttered with outdated files and data, which can slow down your website’s loading speed.

By clearing the cache, you can free up space and improve your website’s speed and responsiveness.

With that being said, let’s dive in!

Step 1: Clearing browser cache

To see the most recent version of a website, it’s important to clear your web browser cache. Many web browsers store static content, such as stylesheets, JavaScript, and images, to speed up page loading times.

However, this can sometimes result in older versions of pages being displayed even after changes have been made.

To clear your browser cache in Google Chrome, start by clicking on the menu icon in the top right corner of the browser. From there, select “More Tools” and then “Clear Browsing Data”.

After these steps, a pop-up window will appear in Google Chrome where you can select the specific content you want to remove from your browser cache.

Be sure to check the box labeled “Cached images and files,” and then click the “Clear browsing data” button.

Congratulations! You have now cleared your Google Chrome browser cache. You can go to your WordPress website to check if it’s loading the updated version of your site.

However, if the changes you made are still not visible, don’t worry.

In the following sections, we will cover additional methods to clear the WordPress cache, so you can troubleshoot the issue and get your website back on track.

Step 3: WordPress cache clearing with your hosting provider

Several WordPress hosting providers offer built-in caching options to optimize the speed of the WordPress site.

To clear the cache of your WordPress website hosted on one of the most popular WordPress hosting providers, follow these steps.

The difference between server cache vs browser cache

Browser cache is a type of caching that happens on the client side, meaning it’s handled by the user’s web browser.

When a user revisits a site, their browser can retrieve cached data instead of downloading it from the server again, speeding up page load time and reducing data transferred.

On the other hand, server cache happens on the server side, meaning it’s handled by the web server or the host. When a user requests a web page, the server checks if there is a cached version of the page available.

If so, under server cache, the server sends a cached site to the user instead of generating a new page.

1.) WordPress cache cleaning with WP Engine

WP Engine, a leading managed WordPress hosting company, offers its own caching solution for users, eliminating the need for a caching plugin.

If you’ve made modifications to your site that aren’t visible, you can clear the WP Engine cache directly from your WordPress dashboard.

To do this, click on the ‘WP Engine’ menu item in the WordPress admin bar, choose the ‘Caching’ option, and then click the ‘Clear all caches’ button.
