    Please help me! I have a major problem with the booking calender. It sometimes generates an error message "Dates unavailable". This message is then directly show in the Google search results. This is a mayor problem, because then Google doesn't rank my page anymore, because Google thinks it has no content.

    Here is the sourcecode when the error occurs:

    if ( jQuery('#submiting1' ).length ) {
    // Disable spinning
    document.getElementById('submiting1').innerHTML = '';
    // Show Error message under the calendar
    showMessageUnderElement( '#date_booking1',
    'Fehler! Wahrscheinlich waren diese Daten gerade von einem anderen Besucher gebucht worden. Bitte laden Sie diese Seite neu und buchen Sie erneut.' ,
    // Scroll to the calendar
    // Enable Submit button
    jQuery('#booking_form_div1 input[type=button]').prop("disabled", false);
    Dates unavailable

    I can send you screenshots. My page is

    Thank you for helping me! 🙂

    • Hello.
      Probably you need to deactivate this option “Checking to prevent double booking, during submitting booking” at the Booking > Settings General page in Advanced section.
      So then this text will not be at the page. But system also will not make additional checking about availability in moment of clicking on “Book now” button.
      Kind Regards.

  2. Hi,

    I have a visitors selectbox working which has capacity for 12 lessons on a day.

    I have the tooltip working in the calendar and it correctly shows the availability.

    If the correct number of visitors is booked it all works correctly and after 12 have been booked it shows that the day is no longer available.

    The problem is if a user tries to book more spots than are available. i.e. I have capacity for 8 left but a user is still able to select 12 from the selectbox. The plugin then throws an error which is displayed on the page "Error during inserting into BD - Dates
    [F:/biz_l.php| L:1892|V:9.Business.Large.SingleSite.8.4.3| DB:Duplicate entry 33-2019-01-25 14:00:01-0 for key " etc

    - Is it possible to update and limit the select box to only show the number of visitors that are available for the selected day?
    - Or on submitting with too many visitors for the day can we avoid showing the DB errror and just show a visitor number error to the user?


    • Hello.
      1) Please open the Booking > Settings General page and in advanced section please set checked this option "Set capacity based on number of visitors",
      then activate this radio button: "Display tooltip on calendar(s) to show availability based on total (fixed) number of visitors for the resource, which can be at free booking resource items."

      2) At the Booking > Resources page please configure your booking resource with 11 child booking resources, so to have total capacity == 12, like this:

      Lessons (capacity = 12) maximum visitors per resource =1
      - Child Lesson 1
      - Child Lesson 2
      - Child Lesson 3
      - Child Lesson 4
      - Child Lesson 5
      - Child Lesson 6
      - Child Lesson 7
      - Child Lesson 8
      - Child Lesson 9
      - Child Lesson 10
      - Child Lesson 11

      3) Watch video about this feature here

      Highly recommend, to check this article about configuration of capacity and availability for booking resources:

      P.S. In case, if you have activated to use "check in/out times" option at the Booking > Settings General page (change over days), so then pelase be sure to set check in time as 14:00 and check out time as "12:00". But usually this "check in/out times" option have to be disabled!

      Kind Regards.

  3. Hello! I have the small business version. In Bookings/Settings/Email/New I only have the option to add one email address. I need to add additional emails so that any new bookings are emailed to a team of folks. How can I add CC emails for the New email. Thanks!

    • Hello.
      You can define the comma separated emails in the field "To" or if you have activated sending copy of emails in these fields at the Booking > Settings > Emails page.

      For example:;

      Kind Regards.

  4. Hi there,

    Is it possible to make bookings using date fields eg. using a "from start date field" and a "to end date field". We want users to request bookings in many coherent days, weeks, months and even years. So it would be a lot easier just to use 2 date fields (from/to date) instead of having to do a marking start date to end date in the calender using mouse. Furthermore the calender seems to have limits in only ranges from 1-180 days - we need 1-several years.

    Best regards

  5. Is the Booking Calendar HIPAA compliant. I don't see any info about that it being compliant. And is the Free download version HIPAA compliant?
    Thank you.

    • Hello.

      Booking Calendar store all booking data inside of the WordPress database, which is saved at your server. So I do not sure that it’s 100% compliant, because of different configurations of customers servers.
      So until now, Plugin is not HIPAA Compliant. Sorry.

      Kind Regards.

  6. Hello!

    When a client of mine hits a reservation in the calendar view and the popup shows, I don't want everyone to be able to see the Email Adress and Phone Number of that Booking. I need that for Data Security reasons. But I don't see any options to configure the Popup.

    Kind regards!

    • Hello.
      You can deactivate to shoe mouse over tooltip and titles in booking pipelines in the TIMELINE view (at your front-end side) by deactivating “Booking details in popover” checkbox at the Booking > Settings General page in Booking Admin panel.

      • Hey!

        I mean I still want the popup to be shown. But without the personal information.
        Email-Address and phone-number hidden.


        • Hello.
          Popover tooltip in the Timeline is showing all booking details that you have configured at the “Content of booking fields data” form at the Booking > Settings > Form page.

          You can deactivate to show tooltip and instead of that shoe yhis specific details in the booking pipeline directly. You can configure it at the Booking > Settings General page in booking admin panel section.

          Other options is not possible in actual versions of Booking Calendar, yet.
          Kind Regards.

  7. WordPress: Version 5.0.3
    Booking Calendar 8.4.3

    Hello! I've tried several times to schedule an appointment from the front end but the email never sends. I've also tried the test email button and have not received anything.

    This shows up when I change the email: "Email different from website DNS, its can be a reason of not delivery emails. Please use the email within the same domain as your website!"

    No one at our school has an email with the same domain as our website as it is hosted by someone else. How can I get this working?

    • Hello.
      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

      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.

      Please note, make testing by creation new booking at front-end side.
      Kind Regards.

  8. Hi. I installed latest version wordpress and booking calender. Everthink works correctly excluded to send booking email to admin.
    1) Firstly check SPAM / JUNK folder in your mail system. //Doesn't come to JUNK
    2) Open Booking > Settings > Emails page and for each email template (switch tabs at toolbar) recheck that you have correct email addresses. // email addresses correct. System sending to visitors email with this.

    Sometimes mail servers block emails, if the address "From" different from the domain of website, from where this email was sending. Its not really depend from the Booking Calendar. So please open the Booking > Settings > Emails page and recheck that field "From" have the same email as your website domain. //Our mail is same with domain
    For example: and not like this
    where its your website domain. //Our mail is same with domain

    Also try to set for field "To" in the "New (admin)" email template the same email that you was used in field "From" at this email template page. // Tried

    Also please be sure that you have activated specific email templates for sending at Booking > Settings > Emails page.
    Check-box "Enable / Disable" must be checked at each email template, that you want to use. //Email boxes checked in All section and use default e-mail template not spesific.

    4) Check that your PHP mail function is working correctly. You can open your login page and try to retry the password, then check if you received email. // Visitors email going already that means php functions works correctly.

    • Hello.
      Its most probably that you are having some JavaScript error at that page. Please recheck your page for any JavaScript errors (usually for see what JavaScript error you have you need to press Ctrl + Shift + J for showing browser console) and try to fix them.
      You can check for the most common issues on the FAQ page at the troubleshooting section.

      You can also 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. May be there exist some conflict with some active plugin or actual theme and just need to find the reason of that issue.

      If you still will have this issue, please send the link to the page with booking form, where you are having an issue, I will check it then.
      Kind Regards.

  9. Hello,

    When attempting to save a Form I receive a Google Chrome Error `this page isn't working` `ERR_BLOCKED_BY_XSS_AUDITOR`.

    I've deleted, and re-installed the plugin.

    I can also confirm the plugin .zip is not corrupted because I've successfully installed it on a test server.
