To edit a course, a “TEACHER ROLE” is required. The “Teacher role” can be set by following the steps below.
1) Click on "Actions menu - More - Users(tab) - Enrolled users" and go to "Participants" page. 2) If users are already enrolled in the course, change the role of the user to “Teacher”. If no users are enrolled in the course, open the “Enrol users” menu by clicking on “Enroll users” button, then enroll the user by setting “Teacher” role.
