Hi Adam. I can install and activate Wordfence Assistant and it does remove all the database tables with the prefix wf (I can see that with phpmyadmin). But when I reinstall and activate wordfence it gives the fatal error again and the website is down. I am installing wordfence from the standard wordpress ‘Add New’ plugin install button, presumably it’s the current version but I can still see the files with names that you mention with mixed upper and lower case letters, like wfUtils.php.
This is a new wp install on a new LAMP server so maybe I missed something when installing LAMP and WP.
– PHP version: 8.0.1
– OS: Linux
– Server software: Apache/2.4.38 (Raspbian)
