I created a new role, and this role should only have the permissions to insert/edit/remove to content types.
The problem is that the admin menu ( Navigation Menu ) doesn't show up in the admin area, and I can't seem to figure out why.
The other problem is that if I login with this user, and access the create node by putting admin/node/add ( since the Navigation menu doesn't show up ), I can create every content type available.
What am I doing wrong?
