Changes and Help with RoundCube 0.5.1

[eltonfranca]

I downloaded and am using RoundCube 0.5.1 on my website, more on the login screen appears instead of login and password appears and the user password. In which file do I change it.

Another question is, when I create a new email in cpanel and enter the RoundCube, so the input box appears, then I'll set up and the other appears, no more lies with the icons in folders just like me. how can I fix these two errors.
