I've been struggling with this all day and I've tried everything I can think of. The real kicker is that when I install the whole package it locally, everything works perfectly. If I point my local installation of InstantForum414 to my HOSTED database instead of my local database, I'm greeted with the above error as well.

Any ideas?
