The way that bp_has_activities is now, you won’t be able to show your friends activity on your own profile page. There’s a few checks to change the type to “personal” if you are viewing your own page or if the current action is “just-me”.

You could, however, duplicate the function (located in bp-activity-templatetags.php) inside your own functions.php file, remove those checks, and call your custom function instead of this one?
