Hi all,
I am trying to restore a course backup taken from a Moodle version 2.9.1+ (Latest build) to another moodle (same version). I am getting the following error:
Debug info: Duplicate entry '219-651-0-0' for key 'mdl_assisubm_assusegroatt_uix'
INSERT INTO mdl_assign_submission (userid,timecreated,timemodified,status,groupid,attemptnumber,latest,assignment) VALUES(?,?,?,?,?,?,?,?)
[array (
0 => '651',
1 => 1427818912,
2 => 1427819038,
3 => 'submitted',
4 => 0,
5 => '0',
6 => 0,
7 => 219,
)]
Error code: dmlwriteexception
I have restored about 14 other courses without issues.
Any ideas will be welcomed!
Thanks a lot.
