I thought I'd jumped through all the hoops; I've managed to get everything integrated on the front end but when I go to access the forum admin section now I get a blank page.
Since being able to access the forum admin section I've changed <?php bb_get_header(); ?> to <?php get_header(); ?> in the bbPress theme files, moved require_once('../wp-blog-header.php'); up to the top of my config file.
If I remove require_once('../wp-blog-header.php'); from my config file I can access the admin section.
Any ideas?
