In the origional index.php in your forums directory copy the code from line 138-211 (thats the lines the code were for an unhacked file at the time the hack was made).

Line 138 should have the following code on it:

PHP Code:

$activeusers = ""; 


And line 211 should have:

PHP Code:

eval("\$loggedinusers = \"".gettemplate('forumhome_loggedinusers')."\";"); 


So you need to copy all the code between those lines.
