 * At line 52 of httpbl.php you need to explicitly cast $results as an (array) to
   prevent an ugly PHP warning at the top of each page which says:
 * > `Warning: Invalid argument supplied for foreach() in /var/www/htdocs/wp-content/
   > plugins/httpbl/httpbl.php on line 52`
 * In other words, it becomes:
 * `foreach ((array)$results as $row) {`
