The regarding hack should be working for all users now. As for the undefined threadedmode errors and such, it's because it appears that the database we're running on now was the test forums DB, which we had been trying vB3RC4 on. However, the normal forums' codebase is RC2... I'm working on this. Unfortunately, I can't fix everything untill I can get on the internet away from work with my laptop, and I honestly can't say when that'll be.
