BuddyPress Integration !
BuddyPress is not working with enabling "Turn WordPress to wpForo".
(Another same issue pending with +1 years 🙁 --> https://wpforo.com/community/how-to-and-troubleshooting-2/exclude-page-urls-issue/ )
Please note, that nothing is working if this option is enabled, not only the BuddyPress.
This option is designed to only use WordPress as wpForo nothing else. All is already described in this option description. You should disable this option. if you want to put forum on home page, you should do this way: https://wpforo.com/docs/root/getting-started/forum-page/set-forum-on-home-page/
