You are logged in as the Emergency User, a special user that can only do one thing: create other users.
The solution is to create a new user using the emergency user, give that user Manager role, and log out. (Quit your browser to make sure there is no HTTP auth caching left). Then log in as the new user you created, and create the objects and/or users you need.
