Where is Facebook users information displayed

1. When a client logs or registers with Facebook where are all the information of his profile shown in FBJ ?

JFBConnect doesn't store any user profile information itself. We rely on importing the user profile data into 3rd party extensions like EasySocial, JomSocial, Community Builder, Virtuemart, the built-in Joomla User - Profile plugin or even your own custom database tables. To import that information, you need to enable the appropriate SocialProfiles plugin and then configure how to import data in the JFBConnect -> Profiles area

2. When I press "create an account" in the login I do not get the register with Facebook

Can you tell me where I can see the page that's missing the Facebook login button?

Thanks,
Alex

That doesn't look like the standard Joomla registration page. If you're using a different extension to manage registration, you'd need to modify the template files for that extension and add the tag below wherever you want the social login buttons to display:The text can be whatever you want as an intro, if you want it.

I hope that helps explain, but should you need anything else, just let me know.

Thanks,
Alex
