error in SQL syntax
-
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 ‘WHEREorder_item_id
IS NOT NULL’ at line 1]
SELECT order_item_id FROM WHEREorder_item_id
IS NOT NULLI 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
