I re-uploaded it, though it's still the same error.
Somehow you've uploaded vBulletin code, we have no way of knowing exactly what you've done here. Go through any files you've uploaded and see where the Vb code is from.
I've also snipped the code from your post otherwise we'll probably get a letter from vBulletin
But how? I've just downloaded the MyBB file and uploaded, and that's it. Currently I've found it in some places.

- Edit Options
-Registration
- Edit User Groups
I've went through my files and they look fine.
Well there's no vB code in the MyBB download, so you will have to have done something here, it wouldn't have come from nowhere.
