    • Hello.

      Please open specific email template at the Booking > Settings > Emails page.
      Then switch email editing from visual mode to HTML (text) mode, and then replace this code:

      Person detail information:<br /><br />[content]

      to this:

      Person detail information:<br />[content]

      Or make some other editing.
      Kind Regards.

        • Hello.
          Sorry, in previous comment, it was not showing HTML tags. I was fixed it. Please recheck.

          I was mean to recheck that you do not have several HTML BR tags (in text view mode (html), during editing email template content), or do not have <p> tag, etc...
          Kind Regards.

          • The code i use does has only one before [content].
            This part of the code is:

            • Please see the screenshot of the actual code here: [IMG][/IMG]

                • Hello.
                  Can you try to check your email with some other email client? Create new booking that will send email to some new email client (if you are using gMail, so then try to send it to yahoo, or some other) and check it. Because its possible that such margin for new line can be set by email client that receive email.
                  Kind Regards.

                  • I tried on hotmail, but its still the same. Check on this screenshot of hotmail, you see that before [content] there are 2 blank lines, instead of one.

                    Do you think there is something wrong with the cod of the [content]? Mine begins with this:

                    Apartment number: [resource_title_hint]

                    • Hello.
                      Please open the Booking > Settings > Form page and recheck "Content of booking fields data" form. Probabaly because it's start with P or DIV element, you re having 2 blank lines there.

                      So to resolve this issue, please open the Booking > Settings > Emails page and remove that &alt;br/> tag before [content] shortcode.
                      Kind Regards.

                    • Hello.
                      Yes, because you are having BR tag just at the beginning, that's why you are having this issue. You need to remove it.
                      Kind Regards.

                    • I just realised there is a in my [content] code!! Thank you!

  1. Everything worked fine until a recent update. I have tried deactivating ALL other plugins but I am still getting "Calendar is loading..." message where the two-month calendar used to show.

    I'm seeing a "prop is not a function" error from the plugin js file but I'm not sure what to do with that.

    I built the theme myself and I do not believe it is loading jquery on its own at all (although it's been several years).


  2. I need an app that will allow my clients to select the dates and times for their five coaching sessions in one singular booking. Can your plugin do that?

    • Hello.

      Unfortunately its does not possible to show dates/times bookings for all your 5 coaching sessions in one singular booking.

      One booking will be for specific date(s) and specific selected time. So if you need to make booking for 10:00 - 12:000 on 2017-06-04 and at 14:00 - 16:00 on 2017-06-14, you will be need to make 2 separate bookings.

      The ability to book for the specific times only possible in the Booking Calendar Business Small / Business Medium versions (and in higher versions for booking resources with capacity =1). Please note if you will make the booking for the specific timeslot, this timeslot become unavailable for the other visitors for that selected date in current specific calendar.

      You can configure the timeslots selections on the Booking > Settings > Form page. Please use the "shortcode generator" on the right side of that page for the correct generation of the shortcode.

      You can use one"timerange" (timeslots) or "start time" and"end time" selections or"starttime" and "duration"of time selections shortcodes or even start time and end time entering shortcodes. Please read more about the booking form fields configuration here

      You can test the bookings for the specific time-slots in action on the live demo of Business Small version (which is configured by default for the bookings of specific time-slots) here: Other live demo you will need to reconfigure.

      Please read the Booking Calendar version overview here:
      Kind Regards.

  3. A question please for business medium.

    I do a reservation on the english version of my site.
    Then an email is sent to the customer, which is in English language.
    Also an email is sent to my gmail, in which i have inside the [moderatelink]. So i press the [moderatelink] code and it transefrs me to the specific booking data on booking listing. Then i press the approve button and another email is sent to the customer. But this email is in greek language! Can you please help me to find my mistake?

    Best regards

  4. Hello,

    Is there a way to add google adwords conversion tracker whenever a person make a reservation (click on the paypal button).

    I have already insert a tracking code on the confirmation page but I want another conversion on the pay button as well.


    • Hello.
      Its possible to insert the code at the "Thank you" page, but its does not possible to insert it into the "payment form", because its generated in ajax request at the same page. We will add this feature to the TODO list for having it in future updates of plugin.
      Kind Regards.

  5. Hi, I bought the small business version for a clients website, After a booking is created, I want a email sent to the managers of the 3 venues, all 3 of them have said they did not received any emails
    need help asap

    • 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.

      Kind Regards.

  6. Hi,

    Can you please tell me where I can edit the Wrong Hash message that appears when trying to edit a booking that has been confirmed?

    Thank you

    • You can delete this.

      Otherwise anyone else having trouble: search 'Probably' in /core/lib/wpdev-booking-class.php

      • Hello.
        You can find this message: 'Wrong booking hash in URL (probably expired)' in the files:
        ../{Booking Calendar Folder}/core/lib/wpdev-booking-class.php
        and in
        ../{Booking Calendar Folder}/inc/_ps/personal.php
        Such message exist 4 times, so you need to replace it several times.
        Kind Regards.

  7. Hi - i followed your guide on how to import my Google calender, but it just won't Work - what to do?

    • Hello.
      Please let test firstly standard manual importing of the Google Calendar events.

      1) If you do not use the latest version 7.2, then please try to update your version to the latest update 7.2
      You can request the new update of paid version of Booking Calendar on this page:

      Please note, in the version 7.0 was an issue with auto import events from Google Calendar into the Booking Calendar. Its was fixed in update 7.1.1:

      May be you was not set your Google Calendar as not public or miss some other item.

      3) After this please recheck that in your Google Calendar exist some events that was not imported previously.

      Then open the Booking Listing page, click on the "Import" button at the "Actions" toolbar and configure correctly parameters in the popup window.
      Be sure, that selected parameters in the popup window fit to your events parameters - select correctly start end end time and be sure that you assigned some booking resource to this public Google Calendar at the Booking > Settings > Import page.
      Kind Regards.

  8. Hello there, i have a strange problem.
    When a customer press the "submit" button, i get on my email 2 emails instead of one.
    The first email is the one that i should get [New(admin)] and hat status unread.
    The second email i get is [New(visitor)], which has a status read! This second email goes also to the customer, but it should go only to the customer...

    Then if do anything on the booking calendar, i receive an email in my inbox. For example if ai approve the booking, the customer gets the [approved] email, but i also get the [approved] email. And this email has the status of read in my email...

    Can you please advice me?

    • Hello.

      Its seems like some specific configuration in your server or in some other plugin, which override standard WordPress wp_mail function. So such plugin or server send copy of any sending emails to your email. Please recheck about this.
      1) Firstly you can try to deactivate one by one all your active plugins at the WordPress > Plugins menu and make testing after each plugin deactivation.
      2) Then you can contact your server administrator or support of hosting about any configuration of sending copy of sending emails to your email address.
      Kind Regards.

      • Thanks for the support! I found the solution...It was some spam filter settings of gmail...

        Best regards

  9. Thanks for a great plugin!

    I'm using the free version and am wondering how I can make sure the booking form uses the css of the theme, so the form will look similar to a contact form on a different page. Could you help me out? Thanks!

    • Hello.
      You can make customization of CSS of booking form at the /{Booking Calendar Folder}/CSS/client.css file.

      Or you can add some custom CSS to the style file of your theme.

      To access booking form field elements you need to use CSS like this:

      .booking_form input[type="text"],
      .booking_form select,
      .booking_form textarea {

      Kind Regards.
