I cannot reproduce it in the cloud version. You can try an upgrade and if this does not help, send me a backup of your database.

Hi Sebastian, I also met the error on adding contributors. I sent the database backup to your message box. Can you help me to check?
Thanks!

I have imported your backup (with the current dev version), but I cannot reproduce it.

Do you mean there is no error in adding contributor?
I cannot edit most function in settings as well. e.g. clients, roles and language

Yes, I do not see any exception, it just works for me. Can you check your logs as well, please?

I got the following error in log.

I think you have to update your MongoDB version.

I see the following error: https://stackoverflow.com/questions/30014243/mongoerror-the-dotted-field-is-not-valid-for-storage

The error comes from the role properties. You can also try to unset them.

I am closing this now because it is related to database issues in both cases.
