  1. Hi

    I use a dark skin on my page and the color of the text for the legend is too dark, is there a way to change this color?

  2. Hello, I need to manage different calendars on the same page for medical appointment services, I understand that I should purchase the personal version, but I do not understand what is the cost per annual or lifetime payment.
    Also, I currently have the free version and it does not allow me to select the current day, could you help me with this issue. If you can give me help in Spanish, I would really appreciate it.

  3. Hello,
    Where can I turn the availibilty off on specific days? For example christmas and new year.

    Kind regard

  4. Thank you.
    We did reduce the amount of bookings we carried in our database to half - but still get the problem "Allowed memory size of 536870912 bytes exhausted (tried to allocate 20480 bytes)"

    The error resulting PHP is .../wp-includes/meta.php Line:1085
    What WPBooking does is: It It sends the admin-mails when a new booking has been made but not the mails to the visitor. This error occcures regardless if the booking is made in the frontend or backend. Not always, but every 5th booking or so.

    Is there anything we can do? We have set-up the memory limits on the server already, reduced the amount of plugins etc. already considerably so that there is not much we can improve on our side.

    • Hello.
      Recheck about the number of season filters that you are using at the Booking > Resources > Filters page.

      Lower number of seasons is better. If you can you can try to make from several seasons, just one season, that will contain several others.

      Also at the same visible page try to use only one booking form (availability calendar) for specific booking resource.

      Clear the bookings in the trash by accessing Booking Listing page and clicking on “Empty trash” button at the Actions toolbar.

      Be sure that this option “ Trash all imported bookings before new import” was deactivated at the Booking > Settings > Sync > “General” page.

      Kind Regards.

      • Thnaks,

        Season filters: We don't use any (Version: Business Small SingleSite 8.8.2)
        Booking forms: We use only one per page
        Trash: was empty already
        "Trash all imported bookings before new import” was deactivated

        So all done. Still the problem persists.

        When we deleted 20.000 old bookings (with PHPMyAdmin like you suggested earlier in this thread): Is it necessary to "compact" or defrag the database afterwards (its MariaDB)?

        Thanks, Frank

          • Thank you - there was nothing left to delete.

            We are still trying to find the problem. In our debug-log we have noticed the following lines that look like having to do with WPBooking:

  5. Hello,
    we have the following problem:
    On one of our WordPress websites, a customer, we have two calendar plugins installed: Booking Calendar (Business Small Version) and Event Calendar WD. Both calendars are critical for the website.
    The problem arises whenever we enable the Event Calendar plugin.
    Suddenly, the booking overview for the Booking Calendar in the backend is shifted right. Meaning it will show the 30th and 31st of the last month and not show the 29th, 30th, and 31s.
    We strongly suspect an unintended interaction between the two plugins.
    It would be highly appreciated if you could assist us in solving this.
    We have also asked the other party for assistance.
    Best regards
    Marie Brunkhorst

    • Hello.
      It’s seems that in other plugin some css (or js) file generate this issue.
      Please check with support of that other plugin, if it’s possible to deactivate of loading css / js files at Booking Calendar pages.
      For example Booking Calendar plugin have such feature to load own JavaScript and css files only at the pages, where you are inserting booking forms.

      Kind Regards.

  6. Buenos días.

    Por algún motivo cuando se hace una reserva de día y hora y tras ser aprobada puede tardar mínimo 2 horas en quedar reflejada en el calendario por lo que los usuarios pueden coincidir en el mismo periodo dos o mas reservas.
    ¿Hay alguna manera de que la reserva se refleje en el calendario de forma inmediata?

    Gracias y un saludo.

    • Hello.
      Please note, curently support and communications possible only in English via emails or at support plugin forum. Thank you for understanding.

      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.
      We just need to find the reason of this issue.

  7. Hello
    We have the following problem on our website
    In the calendar page, the customer has to click on next month to see all current reservations
    Is there a way to see the current reservations without having to lcick "previous or next month" arrows link?

  8. Bonjour,
    le plugin que je viens de mettre à jour emet une erreur à chaque fois que j'essaie d'envoyer un mail , que ce soit au travers de la fonctionnalité de test dans les fonctione de paramétrage ou dans la page de réservation elle même comme suit :

    Erreur! L'e-mail n'a pas été envoyé. Une erreur s'est produite. Could not instantiate mail function.

    • Hello.

      Please note, curently support and communications possible only in English via emails or at support plugin forum. Thank you for understanding.

      Please note, Booking Calendar is use standard WordPress wp_mail function for sending emails. This function can be overridden by other plugins.

      Please check this troubleshooting instruction https://wpbookingcalendar.com/faq/no-emails/

      The most probably you need to check the point #5 from this instruction and install WP Mail SMTP plugin which is 'sending emails via php' option and it can resolve that issue.

  9. Hi,

    I bought the plugin Booking Calendar Business Large (single site usage) version

    I would like to set different colors on the reservations by type of bookings (7 types, 7 colors).
    Types will be : internal reservation, external resa, internal option, external option, under renovation, booked by owner, closed

    I see two way of doing it :
    1. use the booking status field, but I need to add 3 colors/status and a way to specify these types at the booking
    2. via a new field that I can fill when I add a new booking, then I can apply some css based on this new field class

    I need to know how to proceed for one of these cases, you can just point to the easiest way of doing it.
    If you see another way of doing it, please let me know !

    Thanks,
    Adrien

    • Hello.
      Unfortunately in actual versions of Booking Calendar does not possible to show the bookings with such different colors. Sorry. The booking dates table does not have the field for the differnt colors. Sorry.

      Please check more useful info at the FAQ here https://wpbookingcalendar.com/faq/#css

      Unfortunately we can not start, right now, some personal customization or custom development, because almost have no free time.
      Check more about new features here https://wpbookingcalendar.com/faq/need-new-feature/
      Thank you for understanding.

      • I might have an idea using the booking_id field.

        Since it is used as a CSS class "booking_id_X" to display colors in the backend.
        I maybe can set CSS rules to set different colors to different booking_id_X classes.

        I will try to update you here if I make it work !

  10. Hi!

    After inserting a calendar, on the frontpage it says calendar loading. And nothing happens but it keeps on loading.
    Could you please help me sorting this out?

    Thanks,

    rob

    • Hello.

      If its not help, please deactivate your active theme and active the default WordPress theme. And then retest it again. May be there exist some conflict with some active plugin or actual theme and just need to find the reason of that issue.
