Cache Control issue with Litespeed cache?

I’ve moved a website to a different web host. The new host has Litespeed servers, and I’ve switched from the WP-Optimize cache plugin to the Litespeed Cache plugin.

I’ve completely removed the WP-Optimize plugin. The Litespeed plugin is properly installed and works fine.

However, the MainWP Cache Control extension still says that WP-Optimize is installed, and therefore gives an error message when I try to clear the cache via MainWP Cache Control.

Synchronizing, etc., doesn’t help. MainWP Cache Control still sees the old plugin, which is no longer installed.

How to solve this?

Thanks for the help,
Alwin

Hey @Alwin

On the Cache Control Logs page (wp-admin/admin.php?page=Extensions-Mainwp-Cache-Control-Extension&tab=logs), can you check what you see under Status and Cache Solution columns for these affected sites?

Can you please post the community system report from your MainWP Dashboard for review? The report is located in your Dashboard under Info → Server (your-mainwp-dashboard.com/wp-admin/admin.php?page=ServerInformation), on the top right of the page.

Be sure to use the button like the one below; this button hides all your private information:
