Create ssh root password

[ploppy]

For some reason, after a plesk update, I can no longer login to ssh as root using my old password. I have tried to create a user with:

/bin/bash & /bin/bash (chrooted) in plesk

Which lets me login but has no root privileges. How can I either recover my old password or get access to the ssh config to check whether root login is disabled. I installed ssh term in plesk, but that bums out with an error of:

jarsigning exception

Guess it's because there is only the default certificate on the server. I would be grateful if someone could help with this as I have reached a point where I am struggling to find other things to try. Many thanks
