Who's Online problem...

[Warlord]

I'm not exactly sure when it happened, but I think it may have been when we put the .htaccess file in there to rewrite links for member profiles. Anyway, whenever I view who's online, it always says that members are "Viewing User Profile" and then shows the little icon that says "Viewing Error Message" when you hover over it with your mouse.

Anyone know how to fix this?

Have you tried to remove the rewrite rule to see what happens?
