V2.0 Of bbpress, what a great piece of software!
Only bug I have found in developing a heavily integrated site id in the function bbp_close_topic() in /bbp-includes/bbp-topic-functions.php.
The call to bbp_get_closed_status_id() is missing the () at the end, hence PHP thinks it is looking for a constant, not running a function.
My workaround is to place the following code in my theme functions.php file:
define( 'bbp_get_closed_status_id' , bbp_get_closed_status_id() );
Just thought I'd mention as i could not find this anywhere online.
Cheers
Ben
