Hi all,
During a process of solving a duplicating problem I ran into an old forum (https://moodle.org/mod/forum/discuss.php?d=254480) which describes exactly my problem. But the forum doesn't give a straight answer on defining the real problem and a possible solution.
It seems like questions are duplicating randomly during a backup and restore session to make a copy of a course.
Can anyone help me with my problem? I Would be really thankfull if we can find a solution to the problem.
