BuddyPress.org

I would google wordpress appointment plugin

The action is hardcoded, there are a few different functions for linking to profiles, this filter will change profile links but there may be links not using bp_core_get_user_domain.

apply_filters( ‘bp_core_get_user_domain’, $domain, $user_id, $user_nicename, $user_login );

the file entry.php is an individual activity item.

are you getting a white screen or just blank page when you visit /activity ?

its my theme but its so old and outdated I suggest not using it

post on support forum for like plugin and ask developer to add that feature

yes
