How to Clear Your Cache in WordPress (Step-by-Step Guide)

As a WordPress expert with over 15 years of experience, I’ve seen my fair share of caching issues. It’s one of the most common problems website owners face, especially beginners. But don’t worry, clearing your cache is a relatively simple process. In this comprehensive guide, I’ll walk you through everything you need to know about caching and how to clear it effectively.

Caching is like a temporary storage space for your website’s content. It helps speed up loading times by storing static files, like images, CSS, and JavaScript, so they don’t need to be fetched from the server every time a visitor lands on your site.

While caching is fantastic for performance, it can cause headaches when you’re making changes to your website. Sometimes, the cache doesn’t realize your site has been updated, so visitors see an outdated version instead of the latest changes. This is where clearing the cache comes in. It ensures your website visitors always see the most recent version of your site.

Let’s dive into the details of how to clear your cache and make sure your website is always up-to-date.

Understanding WordPress Caching

Before we get into the clearing process, let’s first understand the different types of caching that can affect your WordPress website:

1. Browser Caching

Your web browser stores a temporary copy of website files (images, CSS, JavaScript) to speed up future visits. This is known as browser caching. While efficient, it can cause issues if you’ve made changes to your website and your browser is still displaying the old cached content.

2. WordPress Plugin Caching

Many WordPress caching plugins, like WP Rocket, WP Super Cache, and W3 Total Cache, help improve website performance by creating cached copies of your website’s pages. These plugins can significantly speed up your site, but it’s essential to clear their cache when you make updates or see outdated content.

3. WordPress Hosting Caching

Some WordPress hosting providers offer built-in caching features. These features can be managed through your hosting control panel or directly from your WordPress dashboard. This type of caching can affect your website’s speed and may need clearing depending on your hosting provider and configuration.

4. CDN Caching

Content Delivery Networks (CDNs) like Cloudflare or KeyCDN can significantly improve your website’s loading times by delivering your website’s files from servers closer to your visitors. However, CDNs also use caching, which may require clearing if you’ve made changes to your website.

5. Web Application Firewall (WAF) Caching

If you use a WAF like Sucuri, it can also have a caching layer. Clearing your WAF’s cache ensures it delivers the most recent version of your website to your visitors.

Now that you understand the different types of caching, let’s move on to how you can clear each type effectively.

How to Clear Your Cache in WordPress: Step-by-Step Guide

Here’s a step-by-step guide to clearing your cache in WordPress, covering all the essential types:

Method 1: Clear Your Web Browser Cache

The first step is to clear your web browser’s cache. This ensures you’re seeing the latest version of your website, not an old cached copy. Here’s how to clear your cache in Google Chrome:

Open Google Chrome and click on the three dots in the top right corner.
Select “More tools” and then “Clear browsing data.”
Choose the “Basic” tab and check the box next to “Cached images and files.”

If you’re using a caching plugin, you’ll need to clear its cache. Here’s how to clear the cache in some of the most popular WordPress caching plugins:

Clear Cache in WP Rocket

Go to “Settings” > “WP Rocket” in your WordPress dashboard.
Click the “Clear Cache” button in the plugin’s admin panel.

WP Rocket will clear all your cached files automatically.

Clear Cache in WP Super Cache

Select the “Caching” menu item.
Click the “Clear all caches” button.

You’ll see a “Caching” button in the admin toolbar at the top. Hover over it and click the “Purge All” option.

Bluehost will clear the data from your WordPress cache.

You can clear the SiteGround cache from your hosting control panel or your WordPress admin area.

To clear it from your SiteGround control panel, follow these steps:

Log in to your hosting control panel and go to “Speed” > “Caching” in the “Site Tools” section.
Select the “Dynamic Cache” option from the menu.
Click the menu icon next to your domain name and select the “Flush Cache” option from the dropdown menu.

Method 4: Clear Cache in Your WordPress Firewall Plugin

If you’re using a WordPress firewall like Sucuri to protect your website, it can also have a caching layer. You’ll need to clear this cache to ensure it’s not interfering with your website’s updates.

Clear Cache in Sucuri

Go to “Sucuri” > “Firewall (WAF)” in your WordPress admin panel.
Select the “Clear Cache” option from the menu and click the “Clear Cache” button.

This will clear your Sucuri cache.

Method 5: Clear CDN Cache

If you’re using a CDN, you’ll need to clear its cache to ensure your visitors see the latest version of your site. Clearing a CDN cache typically involves going to your CDN’s control panel and purging the cache.

For example, in Cloudflare, you can find the option to purge your cache under the “Caching” tab in your Cloudflare dashboard. You can choose to purge the cache for a specific URL, all URLs under your domain, or all your cached files.

Bonus Tip: Clear DNS Cache

If you’ve recently moved your WordPress site to a new domain or host, you might also need to clear your DNS cache. This ensures your DNS records are updated, and your website is accessible from the correct location. Here’s how to clear your DNS cache:

For Windows users:

Open the Command Prompt by searching for it in the Windows search bar.
Run the following command: ipconfig /flushdns

For Mac users:

Open Terminal by searching for it in the Spotlight search.
Run the following command: sudo dscacheutil -flushcache

FAQs

What happens if I don’t clear my cache?

If you don’t clear your cache, your website visitors might see an outdated version of your website. This can lead to confusion and frustration, especially if you’ve made significant changes to your site. It can also affect your SEO ranking and user experience.

How often should I clear my cache?

You should clear your cache whenever you make changes to your website, especially if you’re updating plugins, themes, or content. You can also schedule automatic cache clearing through your caching plugin or hosting provider.

Can clearing my cache delete my website’s data?

No, clearing your cache won’t delete any of your website’s data. It only removes temporary files that are stored to speed up loading times. Your website’s content, posts, pages, and database information will remain untouched.

Will clearing my cache affect my website’s speed?

Clearing your cache can temporarily slow down your website as the cached files need to be regenerated. However, this is a minor inconvenience that’s quickly resolved. Your website’s speed will return to normal once the cache is rebuilt.

What if I’m not using a caching plugin?

Even if you’re not using a caching plugin, your hosting provider might have built-in caching features. You should contact your hosting provider to learn how to clear the cache.

Why is my cache not clearing?

If your cache isn’t clearing, there could be several reasons. First, make sure you’re clearing the cache from all the correct locations (your browser, caching plugin, hosting provider, CDN, and WAF). If you’re still having trouble, contact your hosting provider or plugin support for help.

How can I prevent caching issues in the future?

To prevent caching issues, consider using a caching plugin that automatically purges the cache when you make changes. You can also schedule automatic cache clearing to ensure your cache is regularly updated.

How does caching impact SEO?

Caching can positively impact your SEO by improving website performance and loading times. Google favors websites that load quickly, so a well-configured caching system can help boost your rankings. However, if your cache is not cleared properly, it can lead to outdated content being indexed by search engines, which can negatively affect your SEO.

What are the benefits of using a CDN?

Using a CDN can significantly improve your website’s speed and performance, especially for visitors located geographically distant from your website’s server. By delivering your website’s files from servers closer to your visitors, a CDN reduces latency and loading times. This can lead to a better user experience and improved SEO rankings.

Is there a way to clear the cache for all users visiting my website?

Unfortunately, there’s no foolproof way to instantly clear the cache for all users visiting your website. However, most caching plugins automatically clear the cache for specific pages when you make changes. Additionally, you can schedule automatic cache clearing, so the cache is purged regularly. If you’re using a CDN, you can also purge the CDN cache for all files.
