After I add several new users to SS4200-E (18.104.22.168736) and grant them access to shared folders I get very strange users in list (sorry for russian interface, it's users tab):
- I lose all user accounts (about 20). Only admin account survives;
- I can't delete any "param.c" user;
- I can't add any new user (I can fill form, but user didn't visible in list);
- Shared folders - OK (but lose all permissions).
Please, help me to shoot this trouble!!
