Hi Joe…sorry for late reply, I’m just starting my day here.
Anyway, I checked your link you gave me, and definitely do not see anything relating to a comment section. I noticed the other post in the same category does have comments, so something is unique about that one post. Double check the post itself in the editor to make sure the “Discussion” box has a check next to “Allow Comments” is checked.
That is awesome to hear 🙂
Also, no need to feel dense…that setting is often overlooked by many, but WordPress has been known to disable settings without warning (odd I know), and that is one that has happened before for others when the user could have sworn it was enabled.
