https://192.168.1.254:81/app/users was working I setup 2 groups and 8 users and restricted one group to a list of websites for the young kids and anouther group that i just restricted windowsupdates and odd google and ad urls

now I go to edit users and groups and I get
Account system is offline

I am running a proxy and have just figured out how to get the proxy configured per computer and android and different devices and how to restrict all internet to some devices except certain sites. Like blocking samsung from calling home to give private viewing habits and mozilla and clients.google.com

i have been editing and adding tweakn and its been good now all of a sudden this is stopping me from adding more. i rebooted a few times now. This happened after updates.

What can I do?
