I upgraded my Openlitespeed server to run in PHP 8.0. It was fine. the website still runs normally on the front end. but when I go to wp-admin. it says, "There has been a critical error on this website. Please check your site admin email inbox for instructions." Then I checked the email, the WordPress said, "WordPress caught an error with one of your plugins, LiteSpeed Cache." then I deleted the LiteSpeed plugin and installed it again and the website ran normally. but then, I got the error message again.
