It is under Screen Options, of each individual Page or Post:
Pages > Page: [Screen Options] > Discussion
Then untick “Allow Comments”:
[ ] Allow Comments.
To Disable comments on any future Pages or Posts you create, go to:
Settings > Discussion
In the first question — Default Article Settings — disable:
[ ] Allow people to post comments on new articles.
This will make comments disabled by default (unless overridden by individual posts)
Then, to disable them on any old articles, go down to the sixth option under “Other Comment Settings” and CHECK:
[ x ] Automatically close comments on articles older than [______] days
However *set the days to 0* (or 1).
Great. I thought that it could be done either way. It’s strange how many times I think I’ve done it correctly – and have – but it just doesn’t take the first time. Now if I can only figure out how to reduce the font size in the widget title area…
Thanks! Issue is resolved.
