Apologies for the delay in replying.

I’ve made some customizations to the results page /members/member-name/; however the search page is using defaults. To double check, I’ve renamed the override folder inside my theme to ensure that any customizations are being ignored. The results are the same – with BuddyPress Profile Visibility Manager active the user in question does not appear, with the plugin deactivated the user does appear.

Thinking there may have been an issue with the user saving, as site admin, I’ve gone into the User Extended Settings: Users > All Users > username > Extended. Here I set all options (other than First Name and Nickname which don’t give me the option) to Only Me, update, then change Only Me back to Public and save. I’ve tried doing the same logging in as the user with the same results.

It seems to be just for a handful of users on the site which makes it that much more difficult to diagnose. Any thoughts on where to go next?
