How to Install and Configure LiteSpeed Cache for WordPress

Speed matters — visitors leave slow sites, and search engines rank faster ones higher. If your VernalWeb server runs LiteSpeed, the free LiteSpeed Cache plugin is one of the most effective ways to make WordPress fly, serving ready-made pages instead of rebuilding them on every visit.

Step 1: Install the plugin

Log in to your WordPress dashboard.
Go to Plugins → Add New and search for LiteSpeed Cache.
Click Install Now, then Activate.

The moment it is active, caching switches on with sensible defaults — many sites feel faster immediately.

Step 2: Apply the key settings

Open LiteSpeed Cache in your dashboard and enable these safe wins:

Cache — make sure caching is enabled (it usually is by default).
Image optimization — compress and serve images in modern formats. See also optimizing images.
Minify CSS/JS — trims code to reduce page size. Enable one option at a time and test.
Browser cache — stores files in visitors’ browsers; complements leverage browser caching.

Step 3: Test carefully

After each change, visit your site in a private window and click around. If something looks off, undo the last option — minification is the usual culprit, and turning it back off fixes it.

Frequently asked questions

I see “LiteSpeed Cache is disabled”.

That means the server-side cache needs enabling. Our guide on fixing the “LiteSpeed Cache is disabled” error resolves it.

My site looks broken after enabling minify.

Disable the CSS/JS minify and combine options. They occasionally clash with certain themes, and turning them off restores the layout.

Do I need another caching plugin as well?

No — run only one caching plugin. Using LiteSpeed Cache alongside another can cause conflicts.
