The BuddyPress Recent Profile Visitors plugin shows the most recent profile visitors on a user profile as well as the most popular users on a BuddyPress site.
The integration works and requires the BuddyBoss Platform installed and activated on your website.
BuddyBoss Platform is a fork and forge of the BuddyPress plugin and bbPress plugin. Any plugin developed for the BuddyPress and bbPress plugin is supported by the BuddyBoss Platform.
You do NOT need to install the BuddyPress plugin or the bbPress plugin separately. BuddyBoss Platform acts as a replacement for both the plugins.
