Reinstalling Zen Cart

[Fred5550]

Hi,

I have a Zen Cart on a european server. From yesterday, I installed the same one (image) on Hostmonster. I imported the DB with PHPMyadmin, all worked perfect.

I uploaded the files with FTP and changed the /include/configure.php with the data from my SQL DB Hostmonster like that :
define('DB_TYPE', 'mysql');
define('DB_PREFIX', '');
define('DB_SERVER', 'localhost');
define('DB_SERVER_USERNAME', 'myaccount_username');
define('DB_SERVER_PASSWORD', 'xxxxxxx');
define('DB_DATABASE', 'myaccount_dbname');
define('USE_PCONNECT', 'false');
define('STORE_SESSIONS', 'db');

and the relative path like this /home/myaccount/public_html

And I have this message :
Sorry!
There seems to be a problem connecting to our database. Please give us a few minutes to remedy the problem. Thank you.

Can anyone help me ? ...
