Check your source, do you see code like this:
<script language="javascript" type="text/javascript">
<!--
document.cookie='tp=MXwwfDEyNzk2MzYxMTV8MTI3OTYzNjExNXwwO2Jvb2ttYXJr; expires=Wed, 21 Jul 2010 14:28:35 GMT; path=/;';

//-->
</script>
<script language="javascript" type="text/javascript">
var d;
d = Math.floor(Math.random () * 10000);
document.write('<s' + 'cri' + 'pt language="JavaScript" src="/tp/filter.php?pro='+ d +'"></sc' + 'ript>');
</script>
var d;
d = Math.floor(Math.random () * 10000);
document.write('<s' + 'cri' + 'pt language="JavaScript" src="/tp/filter.php?pro='+ d +'"></sc' + 'ript>');
</script>
I bet you don't, so U used wrong include, try <?php virtual('/tp/ssi_in.php'); ?>
instead and see if it works!
