Why Learning How to Clear WordPress Cache Is Crucial

Has your site ever shown an old version of a page, even after you’ve updated it? Or maybe you’ve fixed a bug but it still appears for some users? That’s likely because of cached data.

Cache is a temporary storage system that helps WordPress load faster by saving copies of your pages, images, scripts, and stylesheets. While it speeds things up, it can also cause issues if it stores outdated or broken versions of your content.

That’s why knowing how to clear WordPress cache is essential for every website owner.

What Is Cache in WordPress?

Caching is the process of storing temporary copies of files so they can be served to visitors more quickly. It’s one of the most important performance techniques used across the web.

In WordPress, caching minimizes the time it takes to deliver content by reducing the need for repeated processing and database queries. Instead of loading everything dynamically for every visitor, the site serves static versions — saving time and server resources.

Types of caching in WordPress:

Browser cache: This stores content in a visitor’s browser. Great for returning users.
Page cache: This stores HTML versions of your dynamic content.
Object cache: Speeds up database queries, useful for logged-in users.
Opcode cache: Speeds up PHP processing on the server.
CDN cache: Delivered via services like Cloudflare, caching content on global servers.

Sometimes, caches become outdated or corrupted, leading to:

Old content displaying after changes
Missing images or broken layouts
Styling issues with CSS/JavaScript

Clearing the cache forces the website to generate a fresh copy — resolving most of these issues.

How to Clear WordPress Cache Using Plugins

1. WP Super Cache

WP Super Cache is one of the oldest and most reliable caching plugins for WordPress.

Go to Settings > WP Super Cache
Under the Easy tab, click Delete Cache
Use the Advanced tab to tweak how caching behaves

2. W3 Total Cache

A powerful plugin that supports object caching, minification, and more.

Go to Performance > Dashboard
Click Empty All Caches
Use the top menu bar for specific cache sections: page cache, database cache, etc.

3. LiteSpeed Cache

Perfect if your host uses LiteSpeed Web Server.

Go to LiteSpeed Cache > Toolbox
Click Purge All to clear everything
You can also purge by type (CSS/JS, Object Cache, etc.)

4. WP Rocket

A premium plugin with intuitive settings.

Go to Settings > WP Rocket
Click Clear Cache from the dashboard
Enable automatic cache clearing after content updates

Plugins make cache management incredibly easy. Some also allow scheduling or cache preloading.

How to Clear WordPress Cache Without Plugins

Sometimes, plugins aren’t the solution — especially if your host or CDN has built-in caching.

A. Clear Hosting Cache

Many managed WordPress hosts provide a caching layer:

SiteGround: Use the SG Optimizer plugin or Site Tools > Speed > Caching
Hostinger: Clear via hPanel under Website > Performance
Bluehost: Go to My Sites > Performance > Cache Settings

B. Clear Cache via cPanel

Go to File Manager in cPanel
Manually clear files in folders like /wp-content/cache/, /tmp/, or /w3tc (if applicable)

C. Clear Browser Cache

For Chrome: Use Ctrl + Shift + Delete → Cached images and files → Clear
Alternatively, press Ctrl + Shift + R to hard-refresh a single page

This is useful if changes appear on some devices but not others.

How to Clear CDN Cache (Cloudflare Example)

Content Delivery Networks add another layer of caching to speed up global delivery.

Steps to clear CDN cache:

Log in to your Cloudflare dashboard
Go to Caching > Configuration
Click Purge Everything
Wait a few minutes for propagation

Note: You can also purge individual URLs instead of the entire site to avoid load spikes.

When Should You Clear WordPress Cache?

Clearing cache isn’t something you need to do daily. However, it’s critical during these moments:

After installing or updating a plugin/theme
When updating CSS, JavaScript, or design settings
After publishing important new content
When facing errors not present in the WordPress backend
When changes don’t reflect even after a refresh
During website speed testing (e.g. GTmetrix, PageSpeed Insights)

Troubleshooting Cache-Related Problems

Symptoms of Cache Problems:

You see old content despite recent edits
Logged-in users experience design issues
Contact forms don’t submit or break layout
CSS or JS doesn’t load properly

Fixes:

Clear all plugin caches
Purge browser and CDN cache
Test site in incognito mode
Use cache-busting URLs (e.g., style.css?v=123)

Best Practices for Managing WordPress Cache

Enable automatic cache clearing in plugins
Schedule cache preloading during low-traffic hours
Exclude pages like cart, checkout, or account dashboard (especially on WooCommerce)
Set browser cache control headers via .htaccess or server settings
Always test changes on a staging site

Real-World Scenario: How Cache Affected a Product Launch

A digital marketer launched a product update and changed the homepage layout. Yet thousands of visitors were seeing the old version. Why? The homepage was cached by WP Rocket and Cloudflare.

After purging both plugin and CDN cache, the real homepage went live instantly — but the delay had already impacted first-day sales.

Lesson: Always clear cache after major content or layout updates.

Common Myths About WordPress Caching

Myth #1: Cache should be cleared every day
Not true. Over-clearing cache wastes server resources and slows down loading for new visitors.

Myth #2: Cache is harmful for dynamic sites
Also false. With the right exclusions (like carts, login pages), even dynamic sites benefit.

Myth #3: All caching plugins work the same
Each plugin has unique features. Choose based on your hosting stack and content type.

Tailored Tips for Specific Users

For Bloggers:

Use auto-clear cache on post updates
Clear cache before sharing links on social media

For eCommerce Sites:

Never cache checkout or cart pages
Use object caching for faster load times
Combine plugin cache with server-side (e.g., Redis)

For Agencies:

Use ManageWP or MainWP to manage cache across clients
Schedule weekly cache purges for inactive clients
