Codeigniter and Facebook Login api

[eluser]Unknown[/eluser]
Hi guys.

I have been trying to connect facebook login api into my website for a week.

I have used XTA2 but didn't work. (got 'cannot find the Facebook user' messeage)
here is the link that I used.
http://xta2.ericbae.com/index.php/auth/login

It seems like there is no new application that helps to integrate facebook login api into codeigniter.
as you can see XTA2 is not working anymore.

Is there a simple way to do this job?

Thank you.
