Here is the error that is showing: https://prnt.sc/jxthxo

Background info:
The previous developer coded this theme in his own way. When he finished the site, the client/site owner deleted the developer’s (admin) user profile. When he did, all sorts of issues like this arose. We have fixed most, but I am not sure how to fix this particular issue. The error is displayed in that screenshot, so I was hoping you could help!

You have an overloaded copy of themes/child-theme/buddypress/members/single/home.php it’s calling a function that is no longer used – bp_is_user_forum() this needs to be removed.
