We automatically install and enable the LiteSpeed Cache for WordPress Plugin (LSCWP) on your websites within 24 hours of installing WordPress. LiteSpeed Cache dramatically improves page load times and helps reduce your website's resource consumption.

Note:

• Automatic optimization is enabled only for Shared, Reseller, and Semi Dedicated Hosting.
  
  
• LiteSpeed Cache will not be installed automatically if you have another cache plugin active.
  
  
• No configuration will change if you have installed LSCWP manually.
  
  
• If you want to disable the automatic installation of LSCWP, create a file named [.litespeed_flag] in your WordPress root directory.

Plugin Conflict

Some plugins can conflict with LiteSpeed Cache for WordPress due to duplicate caching and/or optimization features. Please find the list of conflicting plugins here:

https://docs.litespeedtech.com/lscache/lscwp/thirdparty/

Essentially, you shouldn't use more than one optimization plugin. Otherwise, there will be this kind of conflict.
