Our servers run LiteSpeed, so the LiteSpeed Cache plugin can use full server-level page caching — considerably faster than PHP-based caching plugins.
Installation
- Go to Plugins → Add New, search for LiteSpeed Cache, install and activate it.
- Open LiteSpeed Cache → Cache and set Enable Cache to ON, then Save.
Safe starting settings
- Cache → TTL: leave the defaults.
- Page Optimization → CSS Settings: enable CSS Minify and CSS Combine.
- Page Optimization → JS Settings: enable JS Minify first; only try JS Combine afterwards, and test carefully.
- Page Optimization → Media Settings: enable Lazy Load Images.
- Cache → Browser: enable Browser Cache.
Important exclusions
WooCommerce cart, checkout and My Account pages, and any membership or login pages, must never be cached. LiteSpeed Cache detects WooCommerce automatically, but if you use a custom cart page add it under Cache → Excludes → Do Not Cache URIs.
If the site looks broken after enabling
Turn off CSS Combine and JS Combine first — those two cause the vast majority of layout and script breakages. Then purge all caches from LiteSpeed Cache → Toolbox → Purge All and hard-refresh your browser with Ctrl+F5.
Always purge the cache after making design changes, or you will keep seeing the old version.
