These instructions are for clients on one of our WordPress Optimized Hosting plans.
LiteSpeed Cache is a plugin that works directly with our installation of LiteSpeed Web Server and its built-in page cache, LSCache. Because LSCache is built directly into LSWS, overhead is significantly reduced and caching can be done more efficiently than with other PHP-based caches.
Before proceeding please ensure that all existing WordPress caching plugins are disabled.
Start by logging into your WordPress administrative area and select Plugins > Add New from the menu.
Search for the plugin “LiteSpeed Cache Plugin for WordPress” and click on Install Now and then Activate Plugin.
If you are unable to search for the plugin it may be downloaded directly at https://wordpress.org/plugins/litespeed-cache/.
