Missing Manage Fields Link on Content Type Pages
New to Drupal. Working through videos. Got to part on content and the fields to "manage fields" is missing from the list of operations. I only see edit and delete.
Also when I created a new content type there was no option for menu at the bottom of the options to select.
Also I do see any menu options on any of my created content.
I am logged in with my same login that was the admin one I set up with.
Any ideas of what I changed and how to change it back?
