I would like to add a page that uses a custom template (page-coffee-about.php), so it will appear under a custom post type called "coffee". The URL of the custom page should be domain.com/coffee/about/. I already have a URL for domain.com/coffee that uses archive-coffee.php.
I've searched and tried several different things (creating a coffee parent page, adding hierarchical => true to the register_post_type() for coffee, along with supports "page-attributes"), but I keep getting a page not found error.
Please note that I am running WordPress 3.7 and cannot upgrade!
Any help would be greatly appreciated.
