Basically, in the Booking Calendar Free version exist only one default booking resource, and its means that exist only 1 calendar. And if you insert the booking form into one page, like here https://www.meulegoorn.nl/vakantieappartement-in-een-paardenboerderij/ and submit the booking,
so this booking also will be available in calendar, that you can insert into the other page, like here: https://www.meulegoorn.nl/meerdaagse-trainingen-met-je-paard/
The issue of showing different booking days there, because of cache issue. Please recheck for any cache plugins, like “WP Super Cache”, “WP Fastest Cache” or “W3 Total Cache”. If you are using someone, please deactivate it or add the exception to the page with booking form for do not cache this page(s). Otherwise, probably, its because of conflict with some other plugin or actual theme.
Please try to deactivate one by one all your active plugins at the WordPress > Plugins menu and make testing after each plugin deactivation.
If its not help, please deactivate all your plugins and active the default WordPress theme. And then retest it again.
Thank you for your quick reply. I already emptied the WP super cache several times and also my browsercache. In Google Chrome I see the booking on both pages but in the incognito mode of Chrome I see the booking only on one page. I also tested in Firefox and the same there, also on 1 of the 2 pages.
I excluded both the pages of caching but that didn’t help. So therefore I thought perhaps it is not possible to show the booking calendar on 2 pages and have them sync.
But if that is still possible I have to try other things like deactivating plugins.
No, its have to be possible, of course. Its cache issue.
If the deactivation of all plugins will not help, so in this case, please contact support of your hosting about any cache software at your server, and if you are using someone, please add exception to the pages with booking forms to not cache them.
Thanks again. I think I have solved it. Indeed cache problem. I deactivated WP super cache and the bookings on both pages were visible. Although I emptied cache several times without success that was indeed the cause of the problem. Activated the cache plugin again and put on caching and still see the bookings on both pages. Pffff. Glad it is solved.
Thank you for your (again) excellent support.
