 Warning: Invalid argument supplied for foreach() in

 category.php on line 321

 You can get this error when all categories are excluded using the
 available hook to drop categories.


 to fix, cast $categories on line 304 as an array, i.e.:

 {{{
                 $query = "
                         SELECT cat_ID, cat_name, category_nicename,
 category_description, category_parent, category_count
                         FROM $wpdb->categories
                         WHERE cat_ID > 0 $exclusions
                         ORDER BY $sort_column $sort_order";

                 $categories = (array) $wpdb->get_results($query);

 }}}
