I can’t recall where I had found this code, fairly certain on the forums here, but here is a pastebin of the code:
http://pastebin.com/J9whPuCV
It shows category forums and then any forums beneath it, up to one level. It isn’t the entire hierarchical display but could be modified somehow, I would imagine, to show more. How I’m not sure.
You will want to place this file in your child theme in the themes/childtheme/bbpress directory; you’ll want to name the file loop-forums.php
Note: I did change the names of my forum’s columns to Topics, Posts, and Recent, for what its worth.
