Users created but blank pages or errors after register

I'm having some issues with the component. Facebook is the only way to register without problems. Google and Twitter might work but most of the time don't.
As seenin picture below, in the profile list accounts are created, but component doesn't pull images or names and by database, no emails or anything. With twitter after filling registration form page goes blank and the account is created in joomla, so you can login, but there's no account in jfbconnect. It just creates one of the empty lines you see in the image. Google is about the same.

I just tried to create accounts with all my email and none worked. I even got a message about not being able to access a private area of the website. Whatever that means. Only way I managed to create accounts with no problems was by deleting my old accounts and trying again while not logged in to gmail or twitter.

Any idea why those empty users are being created?
