Default exception handler: Fehler: Call to undefined function course_get_format() Debug:
Error code: generalexceptionmessage

• line 4940 of /lib/moodlelib.php: Error thrown

!!! Fehler: Call to undefined function course_get_format() !!!

I added the following line in my local Moodle (in delete_course.php)

require_once($CFG->dirroot . '/course/lib.php');

This seems to have fixed the bug.  Can you please correct this in the Moodle/Repo.

Thanks!
