DATABASE ERROR: CONNECTION FAILED! + roundcube

If you get this error just rectify the login details in the /usr/local/cpanel/base/roundcube/config/db.inc.php file since it's clear the DB connection error.

Example :

------
root@2red [/usr/local/cpanel/base/roundcube]# cat config/db.inc.php | grep roundcube
$rcmail_config['db_dsnw'] = 'mysql://roundcube:DB_PASSWORDlocalhost/roundcube';
// postgres example: 'pgsql://roundcube:pass@localhost/roundcubemail';
root@2red [/usr/local/cpanel/base/roundcube]#
------

PS: Name of the roundcube database : roundcube
DB username : roundcube
DB password : DB_PASSWORD //it has in /root/.my.cnf file

Also give grant privileges to that db.
