Database Connection problem?

Hi all.

I’ve made a terrible error, maybe ??

I’ve changed my-sql password for the user, and now, after change it in the wp-config.php, I still have the message “Error establishing a database connection”, even if I try to connect to wp-admin.

How can I check?

I’ve already updated the wp-config.php with the new password (Mysql), but I still have the same “problem”.

I’ve already check connection, with myPhpadmin, and the database is running and I can connect with the new “credentials”.

Please help me in order to re-put online my internetsite.

Thanks in advance
