members menu not showing

hi

any one have any ideas why my members menu fails to show for members , only admin gets the menu no other members.

if anyone has any clues on why my members menu doesn't work for members but only for admins, i am at a loss, i have cleared cache 4 times, uninstalled the last modules prior to it stopping or at least when i was aware it had stopped. i really need this working.
