I'm not seeing anything in Apache's error log. Just getting a white screen when I go to the admin dashboard.

I'm using PHP 8.3.6 (cli) (built: Jul 14 2025 18:30:55) (NTS). I have full shell access to the machine, so can try anything. (Not using a hosting provider..just using ubuntu server on a PC)
