Hi Ninja
You already have the admin key in ftp host info. In Site admin account info we write down one user credentials but really we have problems to detect the exact step-by-step instructions to reproduce the issue.
I have created an new user to you with some courses with quizzes. You have it in secret info field. Enter to the following url: https://www.auditool.org/cursos-virtuales-auditool/mis-cursos/guruorders and you have two orders with courses. You can do the final exams to try to reproduce the issue. The problem is that this doesn´t happen alltime, our clients notified us only for ramdon courses and not allways happen.
Regards
