My Mautic version is: 5
My PHP version is: 8.2
My Database type and version is: MariaDB 15.1

Your problem
My problem is: I finally got the installation page but after setting up my mautic admin settings and click ‘next’, I get a “Not found” error. Now I can’t get the installation page at all.

These errors are showing in the log:

Steps I have tried to fix the problem:
I’ve reinstalled twice, checked logs, tried docker and tried git clone. I don’t know what else to do.
