The Events Calendar single event page customization guide

Hey 40eleven,
Sorry for the late reply, as I understand you would like your “Tickets” registration section in the event meta sidebar.
The following script will do this, but the sidebar is too narrow for the element, so one way to increase the sidebar width is to increase the page max-width, this css will do this only on single event pages.
Please try this code in the General Styling > Quick CSS field or in the WordPress > Customize > Additional CSS field:

@media only screen and (min-width: 990px) { 
.responsive #top.tribe_events-template-default.single-tribe_events .container {
    max-width: 95% !important;
}
}

Then add this code to the end of your functions.php file in Appearance > Editor:

function custom_event_page_script(){
  ?>
  <script>
(function($){
  $(document).ready(function(){
$('.tribe_events.type-tribe_events').each(function() {
$(this).find('#tribe-tickets').insertAfter( $(this).find('.tribe-events-event-meta.secondary') );
});
});
})(jQuery);
</script>
<?php
}
add_action('wp_footer', 'custom_event_page_script');

The ticket element may look low in the sidebar but that is because the map element is taking space, but it seems unused, if you are not going to use the maps I can move the ticket element up, or even put it at the top of your sidebar.
After adding these please clear your browser cache and check.

Best regards,
Mike
