replace this

$ret = '<script type="text/javascript" src="'.$path.'/track.php?mode=js"></script><noscript><img src="'.$path.'/track_noscript.php" border="0" alt="" width="1" height="1"></noscript>';

with this for xhtml

$ret = '<script type="text/javascript" src="'.$path.'/track.php?mode=js"></script><noscript><div style="display:inline;"><img src="'.$path.'/track_noscript.php" style="border:0;" alt="" width="1" height="1" /></div></noscript>';

or this for html

$ret = '<script type="text/javascript" src="'.$path.'/track.php?mode=js"></script><noscript><div style="display:inline;"><img src="'.$path.'/track_noscript.php" style="border:0;" alt="" width="1" height="1"></div></noscript>';
