Just a thought... I was under the impression that backup and restore was not guaranteed to works "backwards" (i.e. a new version of Moodle to an older). It's a bit unfortunate, but any fix would now be in 1.9.2 and you'd have to upgrade anyway. So, in short, the only solution is to upgrade to 1.9.1+.

hello,
yes that is correct Howard - the backups can be restored only in newer versions. Usually the backups work inside stable branch too, but if there are some major bugs in backup/restore code we can not guarantee that (which was the case in 1.9.0)

We are getting close to 1.9.2 these days, there might be some more backup related fixes this week. I would strongly recommend to upgrade any 1.9.x sites to 1.9.2 when it gets released.

thanks for the report any way
