Wiki server gives 503 error after updating ruby and tails

Hey all.

Wiki services is broken after I updated Ruby and Rails in order to install a log reading dashboard.

Now when I start wiki services (via command line), I get Error Reading Settings, and a 503 error when I try to access the wiki via the web.

We have content in the wiki, so I'm hesitant to just blow it away.

Any ideas where to start troubleshooting this?
