Thanks for answering so fast.
The thing is that, I want to hide comments in a Custom Post Type. Really not in "one", but in all of them. When I created the CRED Form, I checked the "hide comments when displaying this form" option, and actually, in the page where I embedded the form, shows no comments. But, when a user sees the single info of any of those Custom Post Types, the comments area is shown (it is not a page, but a CPT, so there is no "Screen options" tab).
A registered user, can individually hide the comments (from inside the Admin panel), but that is something I don't want. I wish there were no comments shown, but not selecting that option individually, but globally… as if it was part of the template…
Thanks again, I hope you have chance to help me …
