I'm using Moodle 3.5 and I can't delete a course. When I try I receive this report (I activated the debugging):
Eccezione - Call to undefined method mysqli_native_moodle_database::delete_record()
- line 1404 of /lib/gradelib.php: Error thrown
- line 4924 of /lib/moodlelib.php: call to remove_grade_letters()
- line 4840 of /lib/moodlelib.php: call to remove_course_contents()
- line 67 of /course/delete.php: call to delete_course()
Any Idea how to solve it?
Thank you in advance.
