After upgrade our moodle to 2.6 newly created users start getting error "Exception - User not found." when they trying access assignments with checked option Submission types-> File submissions, if teacher uncheck File submissions then newly created users can view assignment, BUT old users in any case have no difficulties with access to assignment.
Please advise
