The wordpress theme I'm using doesn't support comments on one of its custom post types (Shows) and I've been trying to enable them. I added the code below to single-shows.php (copied from shows.php) and it shows previous comments that were already there but doesn't show the comments box to post new comments. I also modified the "supports" for the custom post type to include comments. I checked discussion settings and checked screen options - there's comments but no discussion checkbox.
<?php if ( comments_open() || '0' != get_comments_number() ){ ?>
<hr class="qt-spacer-m">
<?php comments_template(); ?>
<?php } ?>
The site is this.
Here's an example show with old comments appearing:
Here's a post that has the correct comment box and all:
Hope someone can help! This is key to launching the site...

should be enough to display that. maybe your theme do a filter of this part. try with a basic theme to look if you have the same result.
