Caching makes WordPress sites load faster by saving a snapshot of content, but sometimes it needs a manual refresh to show the latest updates or improvements. Knowing how to clear WordPress cache is crucial because it ensures your site is displaying the latest content. Whether you’re making updates, solving issues, or optimizing performance, knowing when to clear WordPress cache is a fundamental skill you need to keep your site running smoothly.

Types of Cache

Browser Cache

Browser Cache is the cache stored directly on your visitors’ devices by their web browsers. It saves elements of your website, such as images and HTML files, so they don’t have to be downloaded again on subsequent visits. This significantly speeds up load times for repeat visitors.

Page Cache

Page caching involves saving the entire HTML output of a webpage and serving that pre-rendered page to visitors. It essentially creates a static version of your dynamic WordPress pages, reducing the need for PHP scripts to run and database queries to be made on every visit, which can dramatically improve loading times.

Object Cache

Object caching is about storing database query results so that the next time a piece of data is needed, it can be fetched from the cache rather than the database. It’s particularly useful for complex queries or sites with a lot of dynamic content. This type of cache can exist both in memory for a single request or persistently to speed up future requests.

CDN Cache

A Content Delivery Network (CDN) cache stores your site’s static assets on a network of servers located around the globe. This means that whether a visitor is near or far from your primary server, they can load your site’s content from a server closer to them, which can significantly decrease loading times.

Clearing Plugin Cache

For WordPress caching plugins like WP Super Cache, W3 Total Cache, and LiteSpeed Cache, the steps to clear the cache can vary slightly. However, you can generally find a ‘Clear Cache’ option within the plugin’s settings in your WordPress dashboard.

Clearing Server-Side Cache

Server-side caching can be more complex, as it depends on your hosting environment. Many hosting providers offer caching solutions that can be managed directly from your hosting account dashboard. Look for options labeled “Cache Management” or similar. Below is a tutorial to clearing server cache using the Page Steady management panel.

Clearing CDN Cache

If your WordPress site uses a CDN like Cloudflare or RocketCDN, clearing the cache usually involves logging into your hosting portal and navigating to your CDN account. Look for options such as “Purge Cache” or “Clear Cache.” Below is a tutorial to clearing Cloudflare cache using the Page Steady management panel.
