bbPress.org

If you have a tool like phpMyAdmin, I think you should be able to log in there and change the site URL.

You used to be able to define the site URL in the bb-config.php as well. This is what used to be in that file:

// The full URL of your bbPress install

$bb->uri = 'http://www.truediy.com/';

Maybe if you put that second line in your bb-config.php maybe that will override the database settings? (Actually, I’m fairly certain that will work. Then you can update the settings in the admin.)
