Course Management the Admin can manage course categories. Authors will only be able to create course in the categories that admins generate in the backend. So there should be at least one course category before an author will be able to successfully create a course. Simply click on the
Manage Categories submenu to display, create and edit course categories. Not that while the admin can delete course categories, they cannot delete categories that have courses. First those course have to be deleted before the category can be removed. You can however edit the category name as necessary.
