We are using Moodle 2.7.1+ (Build: 20140807)
We have been using the Attendance module for years, and our faculty love it. Recently after upgrading our Moodle instance, we found that students received an "Error reading from database" message, if they click on the attendance activity link. Clicking "Continue" will dump the student back to their Moodle entry page. See attached image.
If the Attendance block has been added, students can their individual record of 3 Present, 1 absence, etc.
We have not changed the permissions for students, and everything works fine for the teachers.
Any suggestions of things to check?
