How To Clear The Cache On Wordpress Blog

You've made major updates to your website, but they're not showing up in real time… Now what?

Before you panic, let us tell you the solution is likely simple! You may just need to clear WordPress cache and browser cache in order to see those new changes.

In this guide, you'll learn what cache is and why you may need to empty your WordPress cache.

We're also covering several tutorials to show you how to clear cache in WordPress using plugins, how to clear cached information through your hosting provider, and how to clear browsing data from your web browser.

Spoiler alert: One of the best things you could do to enhance the performance of a WordPress website besides maintaining proper security is to enable caching. Knowing how to clear your cache when needed helps too!

But you also don't have to do this alone. Our team at WP Buffs helps website owners, agency partners, and freelancer partners set up caching solutions, maintain your WordPress site, and more. Whether you need us to manage 1 website or support a 1,000 client sites, we've got your back.

What Is Cache? Plus, How Cached Information Is Stored

Caching systems save and store a static version of your WordPress website. Because of this process, WordPress no longer needs to run heavier PHP scripts and can load your web pages faster. This boosts overall website speed and improves user experience, which both also impact SEO!

As a website owner, you have several ways to store a cached version of your WordPress site. Client-side caching, or browser caching, stores the HTML pages on the user's computer. That means when that user visits your site, the cached version is loaded from that local computer.

Server-side caching stores the static HTML pages on the website server's hard disk or RAM. Typically, this is a method used for very robust websites with multiple databases.

Between the two options, browser caching is the fastest, although server-side caching is still a superior option than not caching at all!

Why We Use Website Caching & Why You May Need to Clear Cache

The reason we use website caching is because it provides an optimal experience for visitors. By sending a saved static copy of the site, your website can load much more quickly with each new visitor.

That said, what's the point in making a website faster if you don't have new content to display to visitors?

People aren't going to visit your website unless you have something compelling or of value to share with them. And people certainly won't return to your website if you don't continually populate it with new content.

👏 While caching is supposed to clear, the second something changes on your WordPress site, that's not always the case. Sometimes, you have to take matters into your own hands. Boom! #WordPress Click To Tweet

When you make new changes to your website, they may not always reflect in real time right away — that's because of the stored cached version of your website.

That means when you make design tweaks or post new content… or there are changes to plugins, themes, or your database, you may need to manually clear your cache in order for visitors to experience the most updated version of your WordPress site.

What Does Purge From Cache Mean?

Purge, delete, and clear your cache are three different phrases all used to explain the same concept. You're eliminating saved information your browser or server has retained from your WordPress site, including cached images, files, and pages. This means, the next time you go to load your website, your browser will be pulling new information from the website server.

It's important to understand this means you'll likely have to re-enter any saved logins associated with your WordPress account… so make sure you have those written down somewhere safe!

After purging all cache, you'll probably notice a change in page load speed. (And we mean slower page speeds, not faster.) Your page speed should return to normal after your caching solution caches the new version of your website, as long as it's optimized.

How to Clear Cache in WordPress Using a Plugin

"How do I clear the cache in WordPress?" Well, WordPress caching plugins are the easiest-to-implement form of browser caching. As a WordPress admin, they're also the easiest caching solution for you to be able to clear cached site data on your own — without help from your website hosting service.

Below are step-by-step instructions for how to clear cache in WordPress from five of the most popular caching plugins.

Clear WordPress Cache With WP Super Cache Plugin

WP Super Cache is one of the less complex plugins, which just means you'll have less control over which cached data can be cleared. All the same, it's very easy to execute!

Click settings > WP Super Cache on the menu bar to the left of the screen. Once you're in the WP Super Cache settings, there are three spots you can delete your cache: the Easy tab, the Contents tab, or the Admin toolbar.

Click the Delete Cache button, and your saved HTML pages will be cleared.

3. Clear All Cache With Siteground

The Siteground WordPress hosting provider offers two ways to clear the cache from their built-in caching solution: from your Siteground hosting dashboard or from your WordPress admin dashboard.

To delete your cache from your hosting dashboard, underneath Site Tools, go to Speed > Caching > Dynamic Cache tab and select the menu button next to the domain name for the site you'd like to delete the cache from. Then press Flush Cache.

Alternatively, you can install the SG Optimizer plugin. Once installed, all you need to do is press Purge SG Cache on the admin bar (or top bar).

4. Clear All Cache With WP Engine

WP Engine provides managed WordPress hosting and offers their own built-in caching system. In other words: no caching plugin required.

You can manually clear your WP Engine cache by clicking on WP Engine on the top bar (or admin bar) on your WordPress dashboard. Under General settings, click the blue Purge All Caches button… and you're done!

5. Clear All Cache With BlueHost

BlueHost is one of the most popular hosting companies… and they make dealing with cache super simple. Their hosting service provides a built-in caching solution that helps to improve your website's optimization and performance.

To clear all cached pages and information with BlueHost, just go to the WordPress dashboard (or your admin area) and find where it says "Caching" on your admin toolbar (at the top of the page). When you hover over that, the option to Purge All should appear. Select that option to purge all caches.

More Tools to Delete Cache Files

1. How to Clear Cache When You Have a CDN

A content delivery network (CDN) provides WordPress websites with an additional level of caching. Basically, a CDN sends a cached copy of your website from one of its far-flung data centers to website visitors that are nearby. So, not only do you benefit from delivering cached content quickly to visitors, you shorten the physical gap between the server and them. (Which makes your loading speeds incredibly fast!)

To clear cache on your CDN, you will have to log into your third-party CDN platform to do so. Check their FAQs for information on how to clear cache for your WordPress site's CDN.

2. How to Clear Cache on Your Reverse Proxy

An HTTP reverse proxy like Varnish or Nginx is another type of caching you may want to purge.

If enabled, you should install the Proxy Cache Purge plugin. There are a few reasons for this:

First, if you want to prevent users on the front end of the site from seeing updates you're making to the website, you can do so in Settings by putting it into Development mode:

This ensures they only see the cached content (pre-update) while you work on the site.

You can also use this plugin if you want to know if caching is working properly:

After you run the test, it will tell you if something like a plugin or theme is creating a conflict and preventing your website from clearing cache properly.

To completely purge a reverse proxy cache with this plugin, use the menu in the admin toolbar:

3. How to Clear Cache on Your WordPress Firewall

A WordPress firewall is technically a reverse proxy, because it reviews and filters traffic before it reaches your website. One major difference, though, is the proxy is meant for website performance enhancements and the firewall is meant for security.

Not all tools available to implement a firewall give you the ability to clear WordPress cache. However, Sucuri Security and CloudFlare are two examples of WordPress firewall plugins that enable cache clearing.

Clear WP Cache With Sucuri Security

If you're using the WP Sucuri plugin, on the menu in your WordPress admin dashboard, select Sucuri > WAF. On the Clear Cache Tab, select the Clear Cache button.

Clear WP Cache With CloudFlare

With CloudFlare you can either clear all cached data or purge cache from a specific URL. When you're logged into CloudFlare, click the Caching button on the top menu bar.

If you'd like to purge everything CloudFlare has stored, your next steps are simple. Click blue the Purge Everything button. A warning pop-up will appear. If you accept, click Purge Everything again.

To clear the cache of a specific page, select the blue Custom Purge button instead of Purge Everything. In the box that appears, select URL in the Purge by field. Enter the appropriate URL in the text box, complete any further instructions in the form, and press Purge.

Ideally, you'll want to set up your firewall plugin to automatically clear the cache when content is updated. You can also use these methods to manually clear cache if you're not able to see updates on your site, though.

4. How to Clear Cache Using the WordPress Command Line

Wondering, "How do I clear my WordPress cache without plugins?" Using the WordPress command line may be one option. However, Using the WordPress Command Line to delete cache doesn't eliminate the page cache, but the object cache — which stores database queries. So only attempt this method if you're looking to flush your object cache.

To do this, execute the following in your WordPress command line:

# Flush cache.

$ wp cache flush

Success: The cache was flushed.

5. How to Clear Browser Cache

Right now, you're probably only thinking about the cached version of your WordPress site, but don't forget that your browser also has a caching system that stores copies of every site you visit. That means to see new changes on your website, you may also have to purge the cache from your web browser.

Here are step-by-step instructions to clear browsing data from Safari, Google Chrome, and Firefox.

Safari Tutorial

Go to the Safari menu by clicking Safari in the top left corner of your screen (if you're using a Mac). In the dropdown menu, select Preferences.

Go to the Privacy tab (with the palm icon). Next to "Cookies and website data," select the Manage Website Data button. Press Remove All.

Google Chrome Tutorial

In the right-hand corner of your screen, click the three dots in a vertical line (the Settings). From there, select More Tools, then Clear Browsing Data.

This is the easiest way to clear your browsing data in Google Chrome, but you can also go to three dots, select Settings in the dropdown menu. You'll be brought to a new page.

In the Privacy and security section, click Clear Browsing Data. Select the Advanced tab. You'll then be able to select specific data you'd like to be cleared from the cache, instead of clearing all browsing data.

FireFox Tutorial

In the top menu bar, select Firefox > Preferences. On the new screen, click Privacy & Security in the left-hand side menu. Underneath Cookies and Site Data, click Clear Data. You can then choose to clear Cookies and Site Data along with Cached Web Content — or one or the other.
