I'm backing up a course from a 2.2 site. The admin user has no role assignments anywhere (I checked). Yet, despite this, the admin user ends up in the backup file.
On restore (on a 2.3 site) there is a very strange result. A screen warning about the admin clash and then some options to set role assignments comes up. However, there is only a cancel button. Pressing the cancel button causes the restore to fail leaving a corrupted course.
Editing the users.xml file and removing the admin user record completely solved the problem.
Does anybody have any thoughts?
