Thanks for the quick reply!
1) First of all try to update your Booking Calendar to latest update 8.1 and Booking Manager to latest update 2.0.2
Updates just ready
Booking Manager updated! Booking Calendar shows that 8.1 is available, but I can’t see how I can update.
2) Please be sure that at the import page, you are using the import shortcode and not the listing events shortcode. In the previous update of Booking Manager was an issue with incorrect inserting import shortcode, if you was used popup toolbar for insrting shortcodes into the posts or pages. So please reinsert these shortcodes or check about it. More info about import shortcode you can find here: https://oplugins.com/plugins/wp-booking-manager/booking-manager-help/#events-import
It does not work with manual import either….
3) Please be sure that you have imported events from booking.com that have dates not in the past. Otherwise, if it was in the past, you can check these bookings at the Booking Listing page in Booking Calendar plugin by switching “Dates” parameter from “Current dates” to “All dates” or “Past dates” in your filter toollbar.
As you can see in the example URL, these events are for 2018.
4) Also please note, the Booking Calendar is import events only once. Its means that you have imported some events, and then edit these events in booking.com (or other website), and then try to import them again, such events will not be imported. You need to completely delete such events and only after that you can start this import again. Its because each such event have unique ID, and plugin does not import events with same ID 2 times.
How do I delete them from the calendar, if they don’t show up in the calendar?
5) Recheck import/export instructions once again: https://wpbookingcalendar.com/faq/#sync
Kind Regards.
