Rouncube Failed Login

[chiefguerra]

Hello all. I'm new here so the help is appreciated.

I installed Roundcube on Ubuntu 12.04, using WEbmin/Virtualmin, using Sendmail, Dovcot and everything installed correctly, i.e. permissions, MYSQL setup and connection ok, etc.

When I try to login I get a failed login error.

Here's my Dovcot config:
rotocols = imap pop3
auth_mechanisms = plain login
log_timestamp = "%Y-%m-%d %H:%M:%S "
#mail_privileged_group = vmail
ssl_cert = </etc/ssl/certs/ca-certificates.crt
ssl_key = </etc/ssl/certs/dovecot.pem
passdb {
  driver = passwd
}
userdb {
  driver = passwd
}
plugin {
  quota = dict:user::file:/var/vmail/%d/%n/.quotausage
  sieve=/var/vmail/%d/%n/.sieve
}
#  user = root
#}
protocol imap {
  mail_plugins = quota imap_quota
}
protocol pop3 {
  pop3_uidl_format = %08Xu%08Xv
  mail_plugins = quota
}
protocol lda {
  mail_plugins = sieve quota
}
disable_plaintext_auth = no
ssl = no

listen = *

Here's my errors log:
