Hi,
Does anyone have the same problem, when attempting to backup a course with users enrolled using Cohort Synch the backup fails. I have no errors, nothing. If I backup the course content only, the backup is successful.
Can anyone help?
It seems that as soon as I have more than 180 users added by cohort sync, backups are no longer possible. Has anyone else come across this problem? Is there a setting somewhere to modify the maximum amount of users?
In the end it was due to mssql!
I did the changes described here : https://tracker.moodle.org/browse/MDL-34744
And now everything works fine!
Hope it will be helpful for someone else!
