I have a similar problem with another theme developed by the same company (Langwitch). Their support is entirely unhelpful and I haven’t found any other solutions for the issue. Basically, their theme bypasses/replaces the page template system with their own page builder so the BuddyPress templates aren’t even loaded for the page specified in the BuddyPress settings.
I am a developer and am willing to work on a solution, but if anyone could give some tips to make this move a bit quicker, that’d be great.
