 * Hi [@ewerkstatt](https://wordpress.org/support/users/ewerkstatt/)
 * Thank you for your interest in the Filter Everything plugin.
 * Please check your PHP version and downgrade it to 8.0 or 8.1

 * It’s on PHP 8.0, but that did not help.
   Is there a way to remove that plugin 
   entirely including its database entries? Then we can install it fresh again.

 * We deleted the plugin using the WP backend (again), now we could install it again,
   and finally it works.
 * Case closed.
