I'm an admitted PHP novice, but I'm wondering if these errors I'm seeing in the Apache logs might have anything to do with the problem:

[Tue Oct 23 00:56:06.695438 2018] [:error] [pid 6569] [client 86.178.195.186:51205] PHP Notice:  Undefined offset: 0 in /var/www/data/webpa211/includes/classes/class_dao.php on line 225, referer: https://webpal.shef.ac.uk/tutors/assessments/reports/index.php?a=BD210F06-0712-3975-6D88-35C94C1ABF0F&md=1540251357&tab=marked&y=2018

[Tue Oct 23 00:56:06.698241 2018] [:error] [pid 6569] [client 86.178.195.186:51205] PHP Notice:  Only variables should be assigned by reference in /var/www/data/webpa211/includes/classes/class_xml_parser.php on line 98, referer: https://webpal.shef.ac.uk/tutors/assessments/reports/index.php?a=BD210F06-0712-3975-6D88-35C94C1ABF0F&md=1540251357&tab=marked&y=2018

As far as I can tell, there haven't been any significant configuration changes to our system. (There've been a couple of updates to MySQL and libcurl, but they both postdate the errors seen above.)

We've had a look on the database and it turns out the user has had the
student role on 2 assessments. Roles look right in Learn and on the
assessment.

Thank you for the suggestions folks, we'll change 'all' roles to tutor,
and see if that fixes the issue. If it does I'll ask our developer if
he's willing to have a go at a fix, and push back to community (he's on
leave just now so I can't commit to that just now).
