I'm in the process of moving my forum and wiki to a new host, and am having issues with the wiki. I thought I had moved over all MW files successfully, and I also thought I made the necessary changes in the localsettings file, but I get this error when I go to the wiki:

Internal error
Detected bug in an extension! Hook vBSSOAutoAuth failed to return a value; should return true to continue hook processing or false to abort.

Backtrace:

Is there any place obvious I should start to look?
