Can you post the lines you added to your wp-config.php and bb-config.php files?

The line defining the secret key in bb-config.php should look something like this:

define('BB_SECRET_KEY', 'My Secret Key');

and in wp-config.php

define('SECRET_KEY', 'My Secret Key');

Don’t forget the BB_ in fron of SECRET_KEY in the bb-config.php file.
