No Control panel after CP 9.0 upgrade

[sheffij]

Hi
After upgrading to 9.0 my control panel disappeared ( https://87.106.128.103:8443/) re-logging in i now get error 500,
I have searched this forum and tried references to mysql and resetting passwords but it doesnt work.

I think Plesk CP has crashed as below

[root@/]# /etc/init.d/psa start
Starting xinetd service... done
Starting named service... done
Starting mysqld service... done
Starting postgresql service... failed
Starting psa-spamassassin service... done
Plesk: Starting Mail Server... already started
ERROR 1045 (28000): Access denied for user 'admin'@'localhost' (using password: YES)
ERROR 1045 (28000): Access denied for user 'admin'@'localhost' (using password: YES)
Starting Plesk... done
ERROR 1045 (28000): Access denied for user 'admin'@'localhost' (using password: YES)
[root@s15251953 /]#

I'm still awaiting a reply from 1and1 can anyone help or resolve this issue please....
