Error Message since a few days


I am getting the following error message, anyone know what I can do to resolve this?

[Google Contacts]Das Hochladen von Elementen auf den Server in Ordner ‘’ ist fehlgeschlagen mit folgendem Fehler: Can not remove all contact group memberships. Contact must always be in at least one contact group.

There was this calendar “contacts” which show birthdays from the calendar. I accidentally created an appointment in this calender. It disappeared and I could not find it anywhere.

Maybe this was the trigger? I don’t know.


Easiest way is to make a backup using Menu > Backup, then go to Menu > Accounts and remove the Gmail account. You can then add it back again, and click on Save & Close.
