I have a very strange (for me) trouble with notifications in OEBS 11.5.10 CU2. One user has sent a message to me. He said that he can't
find his notifications from previos dates, so all his notifications have been lost. However nobody else have a trouble like him. Maybe somebody can tell me what is a reason of this problem. I think that it is a user actions, but I really don`t know what had he did.
