How to install the Wordpress Litespeed cache plugin

What is LiteSpeed Cache and what can it do for me?

So you have installed WordPress and are working to improve the speed of your site and you come across LiteSpeed cache. What is it? What can it do for me? LiteSpeed Cache is a fantastic tool and we fully recommend it's use on your WordPress site as it can dramatically improve the load time of your website and also reduce resource usage on your account. It works by having the LiteSpeed Webserver cache each page, speeding up the load time of your site.

'Caching' means the web server keeps a copy of pages it has already served - and if that page is requested again it'll send the cached copy. This saves the time it take for the server to create that page. This results in a much faster user experience for your visitors.

We recommend only using one caching/optimisation plugin. The LiteSpeed plugin works in tandem with your LiteSpeed web server and is capable of achieving most things you could want from a caching plugin. If you choose to use the LiteSpeed plugin we recommend deactivating and deleting any other caching or optimisation plugins you may have used before.


  1. Login to your WordPress admin panel
  2. On the left, click the 'Plugins' menu item and then click 'Add New'.
  3. At the top right you will find a 'Search plugins...' box, type 'LiteSpeed Cache' then press Enter.
  1. Select 'Install Now' under the LiteSpeed Cache box.
  1. Once the installation has completed, click 'Activate'.


Luckily, the LiteSpeed Cache plugin comes pre-configured out of the box for the majority of websites so no changes need to be made here!

Using the LiteSpeed plugin on Onyx

If you are installing the LiteSpeed Cache plugin for optimisation on the Onyx platform it is important that once installed and activated you visit LiteSpeed > Settings > General tab and disable the cache.

All the optimisation functions will remain active and available, including the Image Optimisation functionality.
