I have a different version of functions.php to you, so I can’t track it down precisely, but my guess is that that line makes a call to $bbdb and that doesn’t exist. Could you check this? You can go to a certain line in Notepad by pressing Ctrl + G and typing in whatever line you want.

If the problem is with $bbdb, it’ll be interesting. I have the same problem (only when trying to load bb from inside wp).

Have you tried putting those lines at the end of config.php by the way? That could circumvent the problem.
