I'm in the process of building a site that makes quite heavy use of custom post types. I've set up my post types to support comments (i.e. I've added
'supports' => array('title', 'editor', 'custom-fields', 'comments') to
register post type()), yet they're showing up as closed in the front end (i.e.
comments_open() is returning false) yet in the WordPress admin area, the comment bubbles are showing up, bold as brass! Any ideas?
