Trying to upgrade from 2.61 to 3.3 - "something went wrong" on dashboard, now HTTP ERROR 500
I tried upgrading from 2.61 to 3.3. It seemed to go fine until I tried to access the dashboard and got the "something went wrong" error.
I tried enabling the default config file, which brought up the Version 3.3 Installer form. That's not what I wanted, so I re-enabled my config file. Now the whole site is down and I'm just getting HTTP ERROR 500.
Any idea where to start?
