Ion Auth - Lightweight Auth System based on Redux Auth 2

[eluser]wgarcia[/eluser]
Hello guys,

I'm new with CI and I downloaded ion auth a few hours ago and installed in a clean CI installation. When I enter the login info (admin@admin.com, password) I get this message:

A Database Error Occurred
Error Number: 1046
No database selected
SELECT COUNT(*) AS `numrows` FROM (`users`) WHERE `email` = 'admin@admin.com'

Am I doing something wrong?
BTW, Ben, I would like to help translating it to spanish.

Thanks in advance
