Course Users: It's possible to change course admin to Student
Course > Users:
It's possible to change a course administrator ( teacher ) to a student, also if no other teacher is in the course.
This causes a course without teacher with some errors when accessing the course administration, for example:
Fatal error: Undefined class constant 'PROPERTY_COURSE_ID' in /var/www/chamilo2/application/weblcms/php/lib/course/course_form.class.php on line 148
The above error is not shown when there is a teacher in the course.
