When you play/change/lost your mysql password, a message is displayed:
**Check your MySQL root password in: /usr/local/cwpsrv/htdocs/admin/include/db_conn.php and /root/.my.cnf
The file db_conn.php is located in /usr/local/cwpsrv/htdocs/resources/admin/include/db_conn.php in my case.
I have experienced problems with that, in example i changed root password and NO dabases where listed. The rest of webpanel remain working. Now i set again all passwords and is working fine
