thanks, disabling files_sharing via occ worked. I can login to owncloud.

But, I am using this feature quite often to share links. How can I get this functionality back?

I had the same problem. Clients were not able to log in but I was allowed to log in as adminstrator and I disabled the file sharing app from the admin panel. Now my clients can log in but can't share the files of course. I hope you fix this soon because file sharing is one of the key reasons we use OC...

Please also post your details in the ticket, the more clues the better :slight_smile:

I have the same problem.

After yum update, it updated to latest version on CentOS 7. The database update went fine, but now I am unable to log in anymore, neither as a user or administrator.

How can I help to supply more information?

How can I disable the files_sharing?
I used sudo -u apache php occ app:disable files_sharing but it did not help.

Kind regards

As this is a known bug and everything is currently discussed in https://github.com/owncloud/core/issues/25557 i'm closing here. Please follow the discussion there until a solution/fix is provided there.

If disabling the files_sharing app doesn't work (people have also reported that at the link) revert to your backup before you have upgraded to oC 9.1.0 for now.
