So what page should I associate with the discussion forums in buddypress if not the forums page as described in the documentation as I’ve pasted below? Even with a forum page titled differently and the slugs named differently (ensuring no duplication) the issue is still present.
Install and activate bbPress.
Proceed to bbPress.org Codex to get started in creating your Sitewide Forums. If you kept the default “forums” slug in Settings > Forums, you can create a new Page via Pages > Add New. Add Title “Forums” and insert the forums index shortcode and/or other bbPress shortcode you’ll find in the bbPress Codex then publish the new page.
Add new “Forums” Page in your custom menu via Appearances > Menu.
