[geeklog-modules] Visitor-Stats

Yes, that is a bug, but I do not remember the exact circumstances of its 
appearing.  To fix it I just tested for an array first.  Thus replace:

--------------------
 arsort($ref);
 foreach ($ref as $key => $value) {
   $retval .= '<a href="' . $refurl["$key"] . '">' . $key . '</a> - ' . 
$value . '<br>';
 }
----------------
with:
--------------
  if (is_array($ref)) {
        arsort($ref);
        foreach ($ref as $key => $value) {
            $retval .= '<a href="' . $refurl["$key"] . '">' . $key . '</a> -
 ' . $value . '<br>';
        }
    }
--------------

Or you can just grab the latest functions.inc from cvs at gplugs.
