Could not connect to MySQL server!

Allright, someone was running a conversion script with PHP on the server. Suddenly, the system goes nuts. Now, after rebooting ISPConfig I get "Could not connect to MySQL server!"

I checked the config.inc.php and the username and password are correct. I also rebooted MYSQL into mysqld_safe and executed the following to ensure it was right:
UPDATE user SET password=PASSWORD("password") WHERE user="root";
FLUSH PRIVILEGES;

There were no modified rows and I exited.

The log files aren't telling me anything.

After entering my username and password at the ISPConfig interface, I get the following:

Warning: mysql_connect() [function.mysql-connect]: Access denied for user 'root'@'localhost' (using password: YES) in /home/admispconfig/ispconfig/lib/classes/ispconfig_db_mysql.lib.php on line 77

Other mysql database driven sites seem to be up and running. They can be accessed and are loading properly.

Ideas? Thanks so much; You all really need a PayPal donate button.

 

Okay, it can connect to the database IF the config.inc.php has a specific IP instead of "localhost" mentioned. However, all other databases can be accessed directly through "localhost" for mysql. What's up with that???
