Unable to login as root on 6.9

I am suddenly unable to log into the web gui as root, sys invalid credentials.

I am able to login to the server via ssh and also with webmin.

Cannot login to Nethserver though.

Any ideas anyone?


Hi John,

here is a thread about a similar problem on Nethserver 7 as a starting point (There are some things you may try like different browsers, check if files are in place and have correct content and so on):

Thanks Marcus,

expand-template /etc/sudoers did the trick.
