Warning 0 => mysqldump: Got error: 1045: Access denied for user 'xxx'@'localhost' (using password: YES) when trying to connect
Error Failure: The database has NOT been saved.
Having same exact issue here:
-4 Zen Cart hosted on VPS
-2 of them upgraded from 1.3.8a to 1.3.9h
-1 has module installed and working just fine
-the other one is giving this error when I try to backup.

More related info:
PHP Version: 5.2.11 (Zend: 2.2.0)
Database Data Size: 6,912 kB
Database: MySQL 5.0.92-community
PHP Safe Mode: Off
MySql Version 5.0.92

I don't see the path to mysqldump on the info page, where can I see it? Even though I don't think that's the problem since the other site on same server is working just fine and I didn't change anything on the files.
