I inherited a v2.5 Moodle.
As Admin, every time I create a new course, it has a 'default' enrolment key present in the 'self-enrolment' settings Eg. Qezvcdg5
All courses have exactly the same key.
Firstly, where is this string coming from? I can't find any setting which would place a default key into every new course.
Secondly, it doesn't seem to work - students still see the 'no enrolment key required'.
In Site administration / Plugins / Enrolments / Self enrolment I have the 'require enrolment key' option disabled.
But I thought that individual courses could use enrolment keys, simply by filling the enrolment key field in their course?
Can anyone explain what might be going on? Thanks.
