Earlier I made a custom post type called ncpage. It’s supposed to be a page-type. To edit the page template for it, I just took a copy of page.php, renamed it single-ncpage.php, commented out the parts about building sidebar and comment sections, and put it in the child theme. It worked fine.
Now with the new way templates work, I can’t figure it out. There are functions for building the template. I’ve tried to track them but can’t find filters or hooks to do the above. Can you help with that?
