    • Salve, stavo aggiungendo delle prenotazioni sul mio sito, ma non riesco a cancellare una prenotazione, come faccio? Grazie

      • Hello.

        You can make cancellation of booking at your admin panel at the Booking Listing page.
        At this page, you can click on "Trash" icon near specific booking to delete this booking.

        If after cancellation of booking you still see the booked date, so then please recheck for any cache plugins, like "WP Super 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).
        Kind Regards.

  2. Hi,
    Just upgraded to v7.0 business single site.
    Is there an option to publish the calendar to google via ics or similar.
    I have had a look and can't see an easy way to do this.

    • Hello.

      1) Booking calendar support only import of events from the Google Calendar (not 2 sides sync).
      Info about it exist in any settings pages at plugin website and at help configuration page of plugin website:
      The export functionality exist in our todo list for some future updates of booking calendar.

      2) Unfortunately, Booking Calendar does not support importing/exporting with other calendars and it's does not support integration with ical/ics, yet. Sorry.
      Also plugin does not support synchronize and integration with , Airbnb, Homeaway, Tripadvisor or VRBO.
      These features exist in out TODO list for future updates. But I can not say about the exact day of implementation of these features.
      Paid versions of plugin support of export bookings to the CSV files.

      Kind Regards.

  3. Hello,

    We make a page with a timeline, on the page people can only see the calendar and can do nothing else.
    But when the user click the button to scroll to the next month, the whole css is gone, and you only see code when you click on a day

    class='label0 label-default0 wpbc-popover-cost'><span etc etc

    Any sugestions?

    • Hello.
      Its seems like some conflict.
      Please try to deactivate one by one all your active plugins at the WordPress > Plugins menu. Then retest it again.
      If its not help, please deactivate your active theme and active the default WordPress theme. And then retest it again.
      Just need to find the reason of this conflict issue.

  5. Hello,
    I am currently setting up a german GmbH within the tourism industry and are looking for a booking system for the website. We are providing tours by vehicle and what we are looking for is a calendar where the customer can choose a specific date and service and thereafter get information what is available to book that week/day.
    We have 1-day tour with 2 different price options and 2-day tour and two different price options and this is something that the customer should be able to choose between.
    We want it to be able to integrate with WordPress and for us to change the colors/type on the calendar which will be on our first page. We also need something to take payments in form of a reservation fees which then will not be the same price as the price set.

    Is this something that we can do with your system? Thanks for the help!

    • Hello.
      Firstly please note, Booking Calendar have the standard booking workflow process, so its can be a little different than you are having in mind about the system.
      Please read the general instruction about usage of paid versions of Booking Calendar:
      You can create the different booking resources ( ), unique calendars - your properties or services at the Booking > Resources page. And then you be able to insert booking shortcode (booking form or availability calendar) for for specific booking resource (your properties or service) into the post or page.

      The different services, (in your case its tours), can be defined as booking resources.
      I do not sure do can you provide at the same date 1-day tour and 2 days tours independently.
      If yes, so then you will be need to have 2 different calendars (booking resources) with booking forms. One for booking of tour for 1 day and other for booking of 2 days tour (the days selection you can define in the different page relative to specific booking form, please check more here: ).

      Please note, if someone will select specific date(S) in calenar and submit the booking, so then this date(s) in calendar will be unavailable for other visitors.

      If you need to define some additional cost that depend form the selected options in booking form (like checkboxes or selectboxes) so then its possible in the Booking Calendar Business Medium or higher versions. Please check more about this feature here:

      The Business Small and higher versions of the Booking Calendar is support PayPal (Standard and PayPal Pro Hosted Solution (please note, PayPal PayPal Pro Hosted Solution its does not the same as PayPal Pro)), Authorize.Net, Sage Pay and iPay88 payment gateways integration, other payment systems are not supporting yet. You can configure and activate it at the Booking > Settings > Payment page.

      You can test Booking Calendar live demos at this page to be sure in functionality and do not have misunderstanding.

      Kind Regards.

  6. Hello!

    I have 2 notifications on my booking calendar, and I cant seem to figure out what it is notifying me about.

    Could you help me figure this out?

  7. Hi - I am interested in purchasing the business version - is it possible to display the cost of selected days under the calendar? As an example, if a day costs $25 and someone selects two days, can it display "Cost $50" before the user submits the form?

    • Hello.
      Such functionality available in the Booking Calendar Business Medium version. In these versions possible to use [cost_hint] shortcode in the booking form at Booking > Settings > Fields page to show total cost in real time. Please test it in live demo of Booking Calendar Business Medium version.
      Kind regards.

  8. Hi,

    I have done a mistake with disable Bootstrap loading at Admin side in advanced settings. Since I can't add bookings from the admin panel and I can't see advanced settings anymore. Is there a way to undo this?

    Thanks for your help,


    • Hello.
      Please open the Booking > Settings General page and in "Booking Listing" section, please UNCHECK this option "Show / hide hints" - "if you want to show help hints on the admin panel." Then click on "Save Changes" button.

      After page will reload, please refresh page one more time (its because during first time, it still will use old settings to show hints). After second refresh of page, you will be able to click on "Show advanced settings of JavaScript loading" link at advanced section and deactivate those checkboxes.

      Kind Regards.

      • Hi,

        I did what you said but it is still the same....

        Do you have another idea?



        • Hello.
          Probably you are still have some JavaScript errors at the page.
          Can you recheck about any JavaScript errors ?

          If you can access to the Developer console, or to Firebug (in Firefox), so then you can use CSS to activate showing section under this link "how advanced settings of JavaScript loading". Then you can uncheck those options and save settings changes.

          P.S. Such issue will be fixed in next update of plugin.
          Kind Regards.

          • I'm not familiar with firebug... Can you tell me how do you do that with firebug?

            Thanks for your time

            • Hello.
              If you in Firefox or in Chrome browser, you can use "Web developer tools".
              In Firefox, please click on "Ctrl+Shift+I",
              then switch to "Console"
              and run this code:


              After this you have to see section with checkbox that you need at the Booking > Settings General page in advanced section.
              Kind Regards.
