wpdb::prepare() warning

  • Hi,

    there is a little issue for me with this plugin version 2.2.3 and WP 3.6
    When I load my page or admin page I get this warning:

    Warning: Missing argument 2 for wpdb::prepare(), called in D:\WEBY\TN\wp-content\plugins\category-icons\category_icons.php on line 1048 and defined in D:\WEBY\TN\wp-includes\wp-db.php on line 992

    Is there some trick how to fix it? (I know I can turn off warnings but it is not the solution).

    Thanks
    Jan
