Hi,

Add this code to your theme functions.php file at the bottom:

add_action('wp_footer', function() {
    ?>
    <script type="text/javascript">
        (function ($) {
            if (typeof $.stecExtend !== 'function') {
                return;
            }
            $('.stec').on('onEventToggleOpen', function (e, data) {
                if (parseInt(data.repeatOffset, 10) > 0) {
                    data.$instance.find('.stec-layout-event.active .stec-form-booking').remove();
                }
            });
        })(jQuery);
    </script>
    <?php
});

This code basically looks if the event is recurrent and if so it will remove the booking form.

Edit the code to:

add_action('wp_footer', function() {
    ?>
    <script type="text/javascript">
        (function ($) {
            if (typeof $.stecExtend !== 'function') {
                return;
            }
            $('.stec').on('onEventToggleOpen', function (e, data) {
                if (parseInt(data.repeatOffset, 10) > 0) {
                    data.$instance.find('.stec-layout-event.active .stec-form-booking').before('<p>The booking has to be made on the first class date</p>');
                    data.$instance.find('.stec-layout-event.active .stec-form-booking').remove();
                }
            });
        })(jQuery);
    </script>
    <?php
});

Have you been updating your theme after entering the code?

Hi,

Could you provide me with ftp to check it out?

Hi,

Sorry for the delay. 

I've cleared your site cache and the problem should be resolved.
