Hello Paul,
your code is not XHTML conformal. There an error is in line 129 in it!
Line 129 with me:
PHP Code:
$whotoday .= "<a rel=\"nofollow\" href='member.php?u=$today[userid]' title='$wrdate' >";
Line 129 is so correct:
PHP Code:
$whotoday .= "<a href='member.php?u=$today[userid]' title='$wrdate' >";
Then also again the XHTML is conformal

I the changed file here attached.
*INSTALL*
