Your issue should be easy to fix!

1. Before going through this process, double check to make sure that the bbpress directory exists under /plugins/buddypress/bp-forums/. It should be there as it comes with a clean install of BP.
2. Assuming that checks out, then the next step is to make sure you have a backup of your MySQL database.
3. Now delete, or in DB parlance, drop the unneeded bbPress tables from your database.
4. Finally, go back to your WP admin screen and navigate to “BuddyPress > Forums Setup” and follow the instructions.

Notes:

There may be a meta record that tells BP that you’ve already installed bbPress. If BP thinks that a bbPress instance has already been installed, you’ll get some verbiage like the following:

“bbPress forum integration in BuddyPress has been set up correctly. If you are having problems you can re-install”

If that is the case, just click the “re-install” link.

A successful bbPress install will have two bb-config.php files. The primary one will live at the root level of your WP install. The second one will be located at /plugins/buddypress/bp-forums/ and is a single one line piece of code to stop unauthorized access to your forums. It should not be an issue to delete the version living at the root level of your WP install as the process of installing bbPress for BP Group forum use creates this file. Do not delete the second, lower-level version of this file.
