Redmine

I moved from 0.7.3 to 0.8.0 and everything appeared to go smoothly except the Wiki. On all projects, accessing the wiki returns:

"Internal error

An error occurred on the page you were trying to access.
If you continue to experience problems please contact your redMine administrator for assistance."

I found this in the log:

Any idea what I broke? Thanks!
