We run a server level caching system for your Managed WordPress Cloud or Hypercharged Cloud Hosting plan called LiteSpeed Cache which is the fastest caching system for WordPress.
In order to take advantage of our server level caching, you must install the LiteSpeed Cache for WordPress plugin.
The LiteSpeed Cache plugin will work together with LiteSpeed Enterprise Web Server at our server level to provide your WordPress website with:
- Extremely fast performance with contents served from server level cache whenever possible.
- Better handling of traffic spike and serve more concurrent users to your website.
- Reduced Resource Usage (CPU, RAM, Disk IO, etc).
- Improved SEO with better loading speed and high PageSpeed score.
Important Notice
To ensure that your website will takes full advantage of our server level caching for the fastest performance, we auto install the LiteSpeed Cache for WordPress plugin for your WordPress website if you do not have any other caching plugin already installed.
LiteSpeed Cache is compatible with most WordPress versions, plugins and themes out of the box so there's nothing that you will need to do to get it to work.
The plugin will not be installed if you already have another caching plugin installed and activated for your WordPress website.
If you do not have any caching plugin installed and you do not want to use LiteSpeed Cache as well (we highly discourage this), you can follow these steps to prevent it from ever being installed for your WordPress website.
Auto Installation of LiteSpeed Cache for WordPress Plugin
If your WordPress website does not have any active caching plugin, the LiteSpeed Cache for WordPress plugin will be automatically installed to allow your WordPress website to communicate with our LiteSpeed Enterprise Web Server to control the caching of your website.
The LiteSpeed Cache plugin will be installed within 24 hours of your WordPress website being moved over or installed in our server.
LiteSpeed Cache is compatible with most WordPress versions, plugins and themes out of the box so there's nothing that you will need to do to get it to work.
What if I already have another caching plugin for WordPress?
If your WordPress website has another caching plugin (For example: W3 Total Cache, WP Super Cache, WP Rocket, etc) installed and activated, the LiteSpeed Cache plugin will not be installed and you will not be taking advantage of the speed boost with our server level caching system.
We highly recommend that you disable the other caching plugin and switch to LiteSpeed Cache instead.
LiteSpeed Cache is a server level cache which bypasses PHP and serve your contents from cache, making it much faster than the other caching plugins.
LiteSpeed Cache also includes Page Optimizations, Image Optimizations and more so you can replace multiple optimizations plugins into one!
What if I don't want the LiteSpeed Cache for WordPress plugin to be installed?
If your WordPress website does not have an existing caching plugin and you do not want the LiteSpeed Cache plugin to be installed, this is something we highly discourage as it will only lead to slower performance and higher resource usage (CPU & RAM).
However, if you insist, you can follow the 2-steps below to make sure that the LiteSpeed Cache plugin will never be installed for your WordPress website:
Step #1: Login to your cPanel, navigate to the LiteSpeed Web Cache Manager page and click the Scan button.
Step #2: Click the Flag button.
And that's it!
By following these steps, the LiteSpeed Cache for WordPress plugin will never be installed for your WordPress website.
You can do this step for any and all WordPress websites that you do not want the LiteSpeed Cache plugin to be installed.
You can always Unflag your WordPress website if you change your mind later.
