bbPress.org

Looks like you still have both activated. You can use both, provided you change link settings for bbPress 2.0.

BuddyPress will claim the /forums/ permalink (and create a page). Try changing your Archive slugs in the bbPress Forums Settings Page (Settings > Forums) to something other than /forums/. /community/ is a good choice.

By doing so, you are effectively using both forum types (groups and site). The group forums will be through /forums/ and the site forums will be through /community/.

If you don’t want both forums types, deactivate the bbPress 2.0 plugin.
