Zenphoto Error

MySQL Error: Zenphoto could not connect to the database server. Check your zp-config.php file for the correct host, user name, and password. Note that you may need to change the host from localhost if your web server uses a separate MySQL server, which is common in large shared hosting environments like Dreamhost and GoDaddy. Also make sure the server is running, if you control it.
