Customization of "Comments are Closed" not working?

Atuhualpa 3.7.13
WP 3.8
www.portraitindonesia.com

This blog is now mothballed. We have transferred the contents to a new domain www.indonesiaetc.com and the project is morphing from a blog about a journey into a site promoting the book written about that journey and the country in which it took place. The original site is hanging around for historical and SEO purposes.

So now we want to
1) Turn off all further comments in the old site.
2) Say in the post footer that the comments are off, but that they continue over at the new site.

1) In Dashboard > Settings > Discussion: I have unchecked "Allow people to post comments on new articles", it appears to have had no effect.
I *have* been able to individually turn off comments on a few posts by using the "Quick Edit" feature from Dashboard > Posts > All Posts menu.
But I'd rather do it globally all at once.

2) In ATO Style & Configure Comments I have changed the text in the "Comments Are Closed text" box to read "Comments are closed here, but continue over at www.indonesiaetc.com" (Actually, I'd like for that URL to be clickable, but that doesn't work either, and I may be asking too much). But that version does not show up.
Here is an example of a page on which I manually closed the comments:
http://portraitindonesia.com/can-ind...care/#comments
As you can see, it just has the default "Comments are closed" text.

Stumped.

Thanks.
