Error on upgrade, no logon possible anymore

Hello, I had to restore 2 weeks old onwcloud folder.
After trying to login again, there was a message saying I need to update to 10.9.1.
But the udpate failed with a error message:

BadFunctionCallException: “creationTime is not a valid attribute”

Does anymore can give me a hint how to processed here?

Thanks Michael

Hey,

i think ownCloud 10.9.1 is pretty old (i think nearly 3 years: https://owncloud.com/changelog/server/#changelog-for-owncloud-core-1091-2022-01-12).

I think it doesn’t make sense to update to such an old version and i think it could be even possible if you update to the most recent version 10.15.0 could maybe not even show this problem.
