So, the password listed in all your configuration files does not match the password set for the ispconfig user.
You can either change the password in phpmyadmin to match what you have recorded, or generate a new password and change your config files.
I would recommend changing the password using phpmyadmin - although its trivial to find all ispconfig files that utilise that password its possible to miss one - I know because I did it!
In phpmyadmin click on users, and you will see the ispconfig user listed. Next to it click edit privileges and scroll down to change password. I *believe* you will be able to enter the plaintext password exactly as its recorded in one of the config files and mysql will automatically hash it.
You will soon know if you have the passwords synchronised - I would expect all of your sql errors generated from dbispconfig table lookups to go away.
