Comments are the most frustrating thing about WordPress. I clicked on an option a while back labled “Block comments from unsecure proxies” and forgot about it. So I sat around wondering why I haven’t received any comments since working with some new themes. What? Nobody likes the new look? I hate not knowing if someone had something to say!
Logged in as the administrator to the site I could post comments just fine. It was only when I logged out to try commenting as a normal user that I saw the problem first hand. Simply cutting off the block unsecure proxy option fixed it.
