If your booking calendars display available dates, but there are no Book buttons, make sure that the option 'Hide reservation forms and buttons' is not ticked in Accommodation > Settings.
If you have created your accommodation types, but they do not appear in the search results, or if their dates are displayed as crossed out on the website, then they are unavailable. For an accommodation type to be available it needs to have:
1) available physical accommodations in Accommodation > Accommodations;
2) a pricing season for the searched dates (Accommodation > Seasons);
3) an assigned rate for the searched dates (Accommodation > Rates).
If one of these three is not set up, then the plugin does not know the renting period and the price, so such accommodation types are considered unavailable.
If you configure these settings, but the accommodation types are still unavailable, please, contact our support team and we will assist with a solution.
