You have to tell bb, when you set it up, where wp is Default assumption is that it’s the same folder. You’re going to need phpMyAdmin or something to fix it.

Go into your XXX_forum database and open up the bb_meta table.

Look for:

user_bbdb_name

user_bbdb_user

user_bbdb_password

The first one is the NAME of your WordPress database (so XXX_wrdp1), the second is the ID used to access said database (sounds like XXX_wrdp1 from your post) and the third is (heh) your password for that ID.

Set those up to point to WP and you should be able to log in.
