Seeking a consistent theme across WP and BBpress, I added:
require_once('../wp/wp-blog-header.php');
to the top of my bb-config.php file.
Everything is looking good from the aesthetic perspective but the bb-admin section now won't load. Also, try and close/move a topic for example won't work as they rely on functions loaded in the admin section.
Should add, I am logged in as the admin. I'm not redirected, just get a blank page, which on my host indicates a php error. Also, I commented out the require_once line in BB-config.php and it went back to working fine (though I then, of course, lose my consistent theme).
Any ideas?
