Site will not load: Fatal Error
 

I know little about PHP* but I'm pretty certain nothing was changed in the admin control panel when this stated* but the site will no longer load and displays the following error:

Quote:
Fatal error: Cannot redeclare tg1() (previously declared in /homepages/37/d218094137/htdocs/x-fan/xfan/index.php(1) : eval()'d code:1) in /homepages/37/d218094137/htdocs/x-fan/xfan/forums/includes/config.php(1) : eval()'d code on line 1

Does anyone have any possible course of action for this problem?
