Hello
We are at version Moodle 3.5.5 (Build: 20190311)
using the New Learning theme. While uploading students in preparation for our new semester, we got this:
The links all point to a final exam in one of the courses students were being uploaded into. When I checked the quiz settings, there was nothing out of the ordinary.
A search on Moodle.org brought up this post (May 2014 - January 2016) and this Moodle Tracker record (December 2017 - still unresolved)
As far as I can tell, the students uploaded into the course without any problems.
