This question already has an answer here:
I want to disable comments on my pages. That means there should be no comment form, no message asking to log in in order to post comments, nothing.
Settings > Discussion is the option "Allow people to post comments on new articles." That implies that disabling comments on pages is possible, assuming that "article" means "post or page."
Unfortunately, a comment form still appears despite my unchecking this box. I thought that the option might be overridden on the page itself, but there are no relevant options on the page edit screen.
I really don't want to hack my theme when the facility to disable comments clearly exists already. How can I accomplish this?
