Thanks CroNix.

Encrypt library loaded (in config/autoload.php)
mcrypt installed on my server
clean cache, cookie, etc.
Nothing. It seems that $this->session->userdata('username') doesn't persist if I switch to another Controller.

Controller 1: create a session ($this->session->set_userdata('username")
Controller 2: If I use $this->session->userdata('username'), it returns nothing.

Thanks again
