I need urgent help.

Well..

Go to my page www.social-bombers.com - When you click at "forums" it goes to someones user profile, all links are fine etc etc.. I believe some tech kid hacked on this shit.

Please check your .htaccess.

 What do i check in htaccess?

if you have never edited your root .htaccess you can replace it with a new one.

 Does that take oway that url rediction ? When some clicks forums, it goes to hes profile at our page for some fucking reason.  (The link is not changed at admin panel, so where is it changed?)

Now i removed that user profile where the direction was going.

 Now when i go to forums or etc, it says "page not found"

What to do?

Just do what Prashank25 said ...

just check if it's changed in any way or just replace the htaccess file if you haven't made any custom changed to it.

Dolphin's known to replace Apache error pages with profiles of the equivalent user ID.  In this case, the profile ID was 500, an internal server error.  You're not being hacked (in response to your other topic).
