OMV 6 Nothing But Dashboard with System Time

I installed a raft of updates today, and when I tried to go back into the GUI, I got a webpage with a dashboard that allows me to monitor the system time. I have access to nothing else. I can't even reboot from the GUI, all I get is Logout. I can SSH in, and every time I reboot, OMV will send me emails telling me that a filesystem does not exist (because a third drive was removed a while ago).

I'm a newbie and tried various things I gathered from the forums to no avail. I'm basically throwing darts at a board.

I tried:

omv-firstaid

2 - Configure web control panel

4 - Reset failed login attempt counter

6 - Check configuration status file - the file is valid

apt-get install --reinstall openmediavault

apt-get install links

apt-get install --reinstall php

df -h

sudo systemctl status openmediavault-engined.service - nothing stands out.

sudo systemctl restart openmediavault-engined.service

apt-get install --reinstall libssl1.1

I've deleted mtime_map in /var/cache/salt/minion/roots/

Any help you could provide would be greatly appreciated.

Wow, I must have changed my password manager and wasn't paying attention when it prepopulated. It never dawned on me that anyone but the administrator could log in to the site. Thanks for your help and for not calling me an idiot in your response.
