- This often happens if you change administrator account parameters in Settings Administrators. First, check this setting.
- Another reason could be a deactivated service (CATV, VoIP, General service) or a function in system settings (SMS, ADLS, IPTV, NAGIOS). So please go through the settings in Settings Active Services, or Settings Syst. settings General.
- The last reason would be a non-existing installation of a module (NetFlow, RADIUS), hence missing related bookmarks and functions.
