Comments Not Posting
There are a couple places comments can go wrong. The first thing to check is on the sidebar of your dashboard go in to Comments and double check to see if any are in there and if they need approved so that they show up on your blog. The first thing to check is under Settings > Discussion, below are my settings on a demo site. Try setting them all them same if they’re different.
Finally, check under an individual post, at the top where it says Screen Options, click that and check the discussion and comment boxes.
Then scroll down past the post content to the Discussion section and make sure “allow comments” is checked.
