I am using the Types plugin and have ticked Categories under the Registered taxonomies that will be used with this post type section. However, no categories seem to appear.
Has anyone encountered this problem before?
Any advice appreciated.
By default, category and tag archives only list Posts in that category. So, despite the UI appearing on the backend, the posts don't show up in the archives. Luckily this isn't too hard to solve.
