Any idea how i can get this solved? The folder is important for that user.

Kind regards

Doesn’t look very fresh your setup. NC 10 is not supported any more, even if there were a bug there wouldn’t be a fix.

Do you use the survey_client? I would just disable it, perhaps this error is completely unrelated with your problem. Then update to NC 11 (https://nextcloud.com/changelog/#latest11), don’t forget the backup in case something goes wrong (especially on shared hosting!).

Hej hej

what is survey client and how can I disable it?. Anyhow, I upgraded to latest version 11. But still the same issue. I cannot access one folder and its content. It still tells me that I have not the required permission:

And when I now try to open a file within the folder an error occur which is telling me something about bad signature:

Annoying… :frowning:

Any idea?

Kind regards

You use the encryption app? Files are signed with data from oc_filecache, if you make manual changes or rescan things, this can break the signature.

I don’t remember that I changed anything and yes, I used encryption. Anyhow, I will accept that these data were lost.

But thank you so much for your efforts
