You are using the excellent Genesis Framework from StudioPress, you have set up a Custom Post Type but – when viewing a single Custom Post Type post – you notice that the Genesis Breadcrumb trail shows the Custom Post Type as plain text, rather than as a clickable link.
For example, the Genesis Breadcrumb trail displayed on a single post in your “Books” Custom Post Type shows this:
Home / Books / An Interesting Book Post
Whereas what you want (or expect) to see is this:
Basically, if you don’t set has_archive to true, then your Custom Post Type doesn’t have an archive, and therefore the Genesis Breadcrumb archive “crumb” only shows as plain text.
