Uploaded – nothing happened

The installation steps, as below, don’t occur for me:

3.Edit the options in Settings > Custom Post Type Page Template
4.Check the custom post types which you would like to use page templates
5.Check the Enforcement Mode depending on themes
6.That’s it! 🙂

Nothing new appears in Settings I do get a CPT CT Manager beneath Settings. I can click on “Create Custom Post Type” and I get a screen asking for the name/slug and to select taxonomy. But when I put in my information and click the “create” button, I am just returned to the same blank screen. I have no idea where the new custom post type has gone, or if it was even accepted.
