My users profiles no longer display.

example of mine: http://nuffworld.com/index.php?option=com_community&view=profile&Itemid=38

However the front page works fine:
http://nuffworld.com/index.php?option=com_community&view=frontpage&Itemid=51

A couple of days ago i change a menu item name from User Menu to user data, because i read that the name user menu and main menu may be causing a problem were it wouldn't show in the menu. I have had user menu not showing but only when it wants to. So i changed it. But that was only in the menu settings and i would assume wouldn't affect the jomsocial profiles.

Any ideas would be very helpful. thanks.

Joomla 2.5.19
jomsocial 3.1.1

Hi Stephen,
I am experiencing problem from both end (frontend and backend).
Can you check the site again please.
Thanks

Sorry about that i got it updated. shouldn't have any issue on frontend or back end.

i completed a site restore instead... Seems the problem may have been way deeper..
