need help fixing an error on the who.php page

[DJ Biscuit]

I created some custom pages for my forum but when you go to them and if someone goes to the who.php page, it says "Unknown Location". How do I fix this to make it say the name of the page?

Search "unknown" "All Mods" "Titles Only" and you will get a mod for 3.7 and 3.6 that will help you.
