Enabling LiteSpeed Cache on WordPress

To enable LiteSpeed Cache on WordPress, install the free LiteSpeed Cache (LSCWP) plugin from the WordPress plugin directory, activate it, and let it connect to the LiteSpeed web server that runs on your ASEOHosting account. Because our servers run LiteSpeed with the built-in LSCache engine, WordPress pages are served from server level cache instead of being rebuilt by PHP on every request, which cuts response time and improves Core Web Vitals.

Why LiteSpeed Cache is different

Most WordPress caching plugins store rendered HTML as files and serve them through PHP. LiteSpeed Cache talks directly to the LiteSpeed web server, so a cached page is delivered by the server itself before PHP or the database is ever touched. This full page cache is the single biggest win for Largest Contentful Paint (LCP) and Time To First Byte. On top of that, LSCWP also handles CSS and JavaScript minification, lazy loading of images, and object caching, so you usually do not need a second caching plugin. Running two page cache plugins at once causes conflicts, so remove any other caching plugin first.

Step by step: install and enable

1. Log in to your WordPress dashboard at yourdomain.com/wp-admin.
2. Go to Plugins, click Add New Plugin, and search for LiteSpeed Cache.
3. Click Install Now on the plugin by LiteSpeed Technologies, then click Activate.
4. Open the new LiteSpeed Cache menu in the sidebar and go to Cache.
5. Set Enable Cache to ON and save changes. Because our servers already run LiteSpeed, the cache activates immediately with no extra server configuration.
6. Load your homepage in a fresh browser tab. To confirm caching is working, view the page source or response headers and look for the x-litespeed-cache: hit header on the second load.

Recommended starter settings

The defaults are safe, but a few tweaks help most sites. Enable them one at a time and re-test, because aggressive optimization can break themes or page builders.

• Page Optimization > CSS Settings: turn on CSS Minify and CSS Combine to reduce render blocking requests.
• Page Optimization > JS Settings: turn on JS Minify. Test JS Combine carefully, as it can conflict with some scripts.
• Media Settings: enable Lazy Load Images to defer offscreen images and help Cumulative Layout Shift when you also set image dimensions.
• Cache > Object: if you have a busy dynamic site, enable object caching. On cPanel accounts this typically uses a local memory backend where available.

For a deeper reference on each toggle, the official WordPress documentation and the plugin settings screens explain every option.

Purging the cache after changes

When you edit content, the plugin purges the affected pages automatically. After large changes such as switching themes, use LiteSpeed Cache > Toolbox > Purge All to clear everything and rebuild from scratch. If you ever see stale content, purge all first before troubleshooting anything else.

Measuring the result

After enabling the cache, run a before and after test with a real Core Web Vitals tool and compare LCP and TTFB. Server level page cache almost always improves both. If your theme is heavy, combine LiteSpeed Cache with a lean theme and optimized images for the best score.
