Roundcube password change issue

[sknd]

I followed this way to change user's email password.But error message is displaying "could not save the new password?

How to fix it please?

$rcmail_config['password_driver'] = 'sql';

$rcmail_config['password_confirm_current'] = true;
$rcmail_config['password_minimum_length'] = 0;
$rcmail_config['password_require_nonalpha'] = false;
$rcmail_config['password_log'] = false;

// SQL Driver options
$rcmail_config['password_db_dsn'] = 'mysql://postfix:'mypostfix_mysql_password'@localhost/sentora_postfix';
// Intended on fleshing this out a bit, but wanted to get something working first
$rcmail_config['password_query'] = 'UPDATE mailbox SET password=%D WHERE username=%u';
$rcmail_config['password_idn_ascii'] = false;
// Also tried making a shell script called dovecotpw that just passes the arguments on to doveadm pw, no difference
$rcmail_config['password_dovecotpw'] = '/usr/bin/doveadm pw';
$rcmail_config['password_dovecotpw_method'] = 'PLAIN-MD5';
$rcmail_config['password_dovecotpw_with_method'] = true;
