Some question about Cb connect

I have a little problem with the link profile with facebook account.
I register an account on the site with a yahoo account that yahaoo account is the facebook acc when i try to link my account through facebook the message say´s "id in use"
When i try to login directly with FB acc say´s "Please complete the username and password fields."
I use CB connect on another site and all works fine.

The other thing i need a custom button to login with Linkedin Is this possible? i need put the button on a custom html because is a very special presentation, and put the button on profile to link existing acc.
Is this possible Thanks.

Sounds like your Facebook ID is tied to an invalid user. Check within CB Connect > Connected to see if your Facebook account is tied to any CB account.

As long as the CB login module is present on the page you can use CB Connect API. For example you can do the below to present a login dialog.

Thanks, i try. I don´t know the problem with CB connect there no are any user with those e-mail. Don´t show any user from hotmail This is normal? The user can register an login whitout problem but on the backend the user is created but on cb connect is not listed, is this comun

Please ensure your Facebook account is a full Facebook account. Business accounts will not work (Facebooks API doesn't return the proper data). Backed under Connected only shows the users that have a connected site ID linked to their account. Please ensure you're using CB 1.8 with latest release of CB Connect (3.3.4).

This is solved, i sincronize users and the login and link works perfect. Thanks
On the conected panel the user only show facebook, linkedin and twitter don´t sow Hotmail.
Is there a way to reimport the picture profile of the user every time use facebook login? i maped the fields but dosn´t works. Is this possible?
Thank you.

By Hotmail you're referring to Windows Live? You need to configure it as instructed in the backend Help. If is already configured ensure it's Enabled.

No.

i maped the fields but dosn´t works. Is this possible?

Don't map the avatar field; that is synchronized automatically if a Facebook avatar can be retrieved. Mapping only works for registration. It does not fire after login and it does not fire if you link to an existing account.
