Hi,
TQCSI has been using the moodle in order to manage exams.
often, we will check on the folder for a specific standard and use this to check the grades of people who have taken the exam.
I'm no developer so i am not sure why we have begun encountering database errors, this seems to only be occuring for 2 exams, despite nothing being done differently from other exams.
When putting the website into debug menu, the section that is meant to be displaying staff member grades, displays the following:
Error reading from database
