Yeah Mr Hunt .. considering that for long term solution, Thank You. Just looking for temp and fast solution for the issue as the lect will redo the quiz again in 3 days time. Downtime only can be done on weekend.
The student number is just 118 person ( this never happen previously in moodle 1.9 and mysql 5 )
Mr Hunt would it better to upgrade to 2.5 from 2.3.1 ?
