Reply To: Cannot add Custom Post Type

Sorry, that's what I meant.
I'm trying to create a new custom post type using the mb custom post type plugin. It appears as a button in the dashboard under Meta Box. I can click on it and it takes me to an empty table where my custom post types would be if I had created any, which is what I would expect.

The problem is that when I press "New Post Type", at the top of the page, it takes me to an empty page with nothing but a publish button. The title of the page is Add New Post Type. I have read the tutorials and there should be some sort of table where I can put the details of the custom post type I'm trying to create.
