Occasionally, we have a blog owner trying to enable commenting, on a blog - and being unsuccessful diagnosing commenting problems . Checking the per blog comment settings, in the the dashboard menu under Settings - Posts and comments, there's no obvious problem. The problem, in some cases, is in the per post settings, in the Post Editor "Post settings - Options" wizard - but not all posts will have a problem. The "Reader comments" setting, for any new post, is taken from the setting for the previously published post. If you publish a post today, with "Reader comments" selected as "Don't allow", the next post will also be set to "Don't allow" - unless you change the setting, before publishing. Similarly, if it's set to "Allow", the next post published will have it set to "Allow". Allow Don't allow That's the choices, for each new post.
