Oh Dear.. Files not connecting to peoples profiles.. help!

Ok guys if someone could help me out on this one it would be much appreciated.

So suddenly out of nowhere I notice that when I click on someones profile on my elgg 1.8 site and click "files", or "bookmarks" so I can view what files or bookmarks the particular user has uploaded... I get a message saying "no files". Does anyone know how I might fix this, or what is causing this issue?


Thanks in advance.
