Where did you “solve” this @patrickeidemiller? Where did you “comment out” these lines? Looks like .htaccess. How is this connected with the SQL error?

I have the [exact same problem](https://forum.mautic.org/t/as-usual-upgrade-to-4-2-2-this-time-effed-up-my-installation/24106/5) as the start of this thread and don’t see a clear solution here.
