What WordPress version are you running? Since version 1.8 Cache Enabler now requires WordPress 5.5 or higher.

Ignore that, I see what the issue is here and will fix it shortly. Loading a WordPress admin page instead of a frontend page will fix it.

I couldn't even get to the admin page. i had to have the hosting company disable the plugin from their end to get the site back up.
