cannot view profiles, blank

[Chadi]

I just realized today that I cannot view various profiles. I get a blank page, but I can view others' profiles strangely. I tested it as unlogged and logged in as another member.

I confirm it is not vbseo and I did not install any new plugins. I was able to view just an hour ago to view an unread visitor message.
