Interesting. The way we have it working on our site is that it becomes it’s own page at the creation of the recipe.
So if I make a cookie recipe — you would go to:
https://example.com/this-is-my-cookie-recipe-title — and comments are turned off. For the life of me I can’t force it to on.
On my single.php all posts created by our bloggers have commenting on by default — this is the only exception. It’s driving me crazy trying to figure out what the developer did on this site.
I’m working on it after the fact.
