I am using Moodle 2.4.
I had issues on my end with uploaded quizzes containing inaccurate information. We made new quizzes for about 6 different courses. The original question bank and quizzes were successfully deleted and new question bank and questions successfully added.
The issue is: the system seems to be reverting back to the old questions and old question bank after a few months. All of the new questions are no where to be found and I am forced to re-upload the corrected files.
This has been happening with the same courses for well over a year in a very consistent manner.
Any ideas would be greatly appreciated.
