Hi,

Replace file stachethemes_event_calendar\front\view\single.php with the one I've attached.

Can you give me ftp access to the files to do it for you? You can post here privately.

Direct FTP access is safer since any php typo could produce an error which cannot be undone from the admin but I'll try be careful.

Hi,

I've added additional code to your theme functions.php file:

add_action('wp_footer', function() {
    ?>
    <script type="text/javascript">
        (function ($) {
            if (typeof $.stecExtend !== 'function') {
                return;
            }
            $.stecExtend(function (master) {
                $.each(master.calData.eventsPool, function () {
                    if (this.category.length > 0) {
                        this.color = this.category[0].color;
                    }
                });
            }, 'onAddToEventsPool');
        })(jQuery);
    </script>
    <?php
});

This code changes the color of the events in the calendar as well.

Single page code is working as intended: http://test02.igmetall.de/stec_event/test/

You are right it's common for users to request this so we'll most like add it in the options.
