Have a problem with profiles

Ok it is just my site so no worries.. But when I goto a different members profile. The click on the there info in the members bar.. Then the members bar turns into my profile? All the rest of the links there are set as me? Where would I go looking for the problem there? I have a very heavily moded site.. I really don't want to un-install all the mods again to find out if it is one of them again..
