 * Running sub-domain Multi-site install, WP 4.0, with wp_debug on it prints the
   following:
 * Notice: wpdb::escape is deprecated since version 3.6! Use wpdb::prepare() or 
   esc_sql() instead. in ../../public_html/wp-includes/functions.php on line 3206
 * Searching around I’ve found nothing related to this so am curious if anyone else
   has experienced it and if so what they’ve done to resolve it?

 * It’s probably caused by a plugin or a theme. Since it’s a deprecation warning,
   you generally tell the dev to please fix 🙂
