First, I did a search and found answers, but they seem inapplicable.
Second, my problem:
I have a new blog using WP 3.0.1. At the end of each post it says, "Comments off", despite the Dashboard-->Settings-->Discussion-->Discussion settings are all set to allow comments to be posted.
"Allow people to post comments on new articles" is checked.
In the "Other comment settings" section, nothing is checked except enabling nested comments. Therefore, no one has to fill out a name and email address, or even be a prior commenter.
The only other thing that is checked is that I get emailed whenever someone posts a comment.
So, what's wrong? My blog was imported from Blogger, where I did have comments moderated. Is that somehow interfering?
