Hi,
I did not find any special changes for bbPress permissions/capabilities inside WOffice theme. It seems something is changing during BuddyPress/bbPress integration. Is it possible to get admin access to your site?
If Yes, I would make a copy of files and data to setup a copy at my development environment and look what is going with bbPress permissions using your exact site settings/configuration. If that’s applicable, send URL and login credentials to support [at-sign] role-editor.com
