XF 2.3 500 Error Mid Upgrade

[dvduval]

I ran the upgrade and got a 500 error for the whole site. Everything is down. What would be the steps to troubleshoot?
It's for dance-forums.com

Found this in the error log

XF 2.3 is stable, there is no critical bug and many forums are running it without major problem.
Concerning the upgrade there is an issue, severe enough from my point of view for it to deserve a warning notice, with caching on server side, and you suffered it, unfortunately.

Yes, I agree so far that it is stable (after the upgrade is complete).
