Our demo website is running an old version of BuddyPress and the forum style you see there is for BuddyPress group forums, something that is no longer available because BuddyPress now uses bbPress to power its forums. When BuddyPress made that switch (a couple of years ago) we did our best to keep the new forum style in keeping with the rest of the Razor theme, but there were a number of BuddyPress-related elements that were no longer available; i.e. the newer bbPress forum style can’t look exactly like the old group forums because of differences in the code structure.
