When I want my site to be free of comments, completely, nada, I need to edit the theme. “Comments are closed” is not at all what I want – I don’t want comments AT ALL and no declaration that there are no comments. I suggest to add a variable that authors fo themes can test (and users set) such as no-comments-on-any-post, say, so they can remove the call to comments_popup_link() in that case.
I’ve tried this PHP code and it doesn’t turn off the comment mark in the blog. Still shows “No Comments” which is what i was trying to shut off as well. Is the code to be somewhere very specific in the PHP script?
