For anyone else struggling to get BB Press and Thesis 2 to work (ie forums page showing blank) see these instructions:
“the problem in this case isn’t with Thesis per se, it’s just that you have to configure the Template being used for that page in a specific way in order for it to work with bbPress:
Launch the Thesis Skin Editor and access the Forums template (i.e., the one which is nested under the Archive template).
Expand the Post Box in that Template, and then remove all of the boxes which are currently inside of it.
Then, click “show tray” at the bottom of the Post Box, and click on Post Box → Content to add that dependent box to the parent Post Box; then save the template.
Once you’ve done that, view the page at /forums/ again, and you should then see the Forum Index displayed on that page (assuming you’ve not changed the plugin’s default “Forum root to show” option).”
