Our plugin relies on hooks normally included in the default page template for The Events Calendar’s single events. If you have made a custom template for the single-event.php file, you will want to make sure the following php hooks are included:
<?php do_action( 'tribe_events_single_event_before_the_content' ) ?>
<?php do_action( 'tribe_events_single_event_after_the_content' ) ?>
