I have configured Custom Fields plugin to work with Custom Post Types and it has worked perfectly. But after two weeks it randomly stopped working – there is no custom fields at the bottom of my Custom Post Type and when I go to Custom Fields Groups I see my Custom Post Types instead of Custom Field Groups!

What kind of nonsense this is? I have attached the image. So I can’t add any new Custom Field Froups and somehow Custom Posts are listed there.

Maybe it has connection with my Taxonomy name, because I have named them “Item”, “Items”. Maybe in Database something wrong has happened and posts list appeared in Custom Field Groups?
