 * Hello!
    I installed wordpress 4.9 and activate plugin “WP Hotel Booking” (You
   can use any theme – for example “Twenty Fifteen”). I come to front end and press“
   Customize” – I can see customizer panel on left side and error text on right:
 * Notice: Undefined property: wpdb::$hotel_booking_order_items in C:\xampp\htdocs\
   wpserver…\wp-includes\wp-db.php on line 625
    WordPress database error: [You have
   an error in your SQL syntax; check the manual that corresponds to your MariaDB
   server version for the right syntax to use near ‘WHERE `order_item_id` IS NOT
   NULL’ at line 1] SELECT order_item_id FROM WHERE `order_item_id` IS NOT NULL
 * I did not see this error in wordpress 4.8.3
    I think it is in files thank-you.
   php and booking-details.php or maybe more. Thanks
