Same problem here. I tried everything for more than a few days. I even contacted my host because I thought it could be a virus.

It is working fine without the W3 Total Cache.

I also believe WP 3.9 was the culprit. This was the issue :

2014-05-29 07:23:23.859 [NOTICE] [xx.xx.xx.xx:xxxxx-2#APVH_example.com] mod_security rule triggered!

Problem fixed via the server. ModSecurity rule was being triggered.

For the printing issue… Make it inside a loop and it will work. Great plugin from Joshua but his documentation needs to include this tip.

This is how you’d make it work:

<div id"something">
<?php if (have_posts()) : ?>
 <?php while (have_posts()) : the_post(); ?>
  <?php multieditDisplay('YourBlockName'); ?>
 <?php endwhile; ?>
<?php endif; ?>
</div>

That is because you have no single.php in your ‘stonier’ template directory. Create even an empty one and everything will get fixed.

@niraj – Try this:

<?php echo get_the_term_list( $post->ID, 'location', '<p>Location  : ', ', ', '</p>' ) ?>
<?php echo get_the_term_list( $post->ID, 'duration', '<p>Duration  : ', ', ', '</p>' ) ?>
<?php echo get_the_term_list( $post->ID, 'courses', '<p>List of courses  : ', ', ', '</p>' ) ?>

You might probably use it in your single-custom-post-type.php just around <?php the_content(); ?>
