I have been trying different themes, and I just noticed "Comments closed" on every post. I know that it wasn't always that way, but I went back to the previous theme and then back to one from further back.
- Boldly Blue
I recently deleted two comments. Can that close them on all posts? I verified on two of them that comments should be enabled. Even though they aren't custom post types, I tried the trick in Why are the comments disabled by default on my custom_post_types? but no change. Also looked at Comments enabled, but disabled at the same time but I'm reluctant to add code just to restore something that shouldn't have gone away.
