Since upgrading WordPress to version 3.5 and Events Manager to the latest version, auto embed of YouTube/Vimeo movies doesn't work anymore.
I previously used
<?php the_content(); ?>
to display the event or location content. This didn't work anymore.
Now I changed single-event.php and replaced it with
<?php echo $EM_Event->output('#_EVENTNOTES'); ?>
This shows the content, but doesn't convert a YouTube url to a movie.
What is the right way to get this to work again?
