Can you let us know more about where it's not showing? If you're using the SCLogin module as your login module, then the social buttons should show automatically for any social networks that are configured.
If you're expecting the buttons to show on the EasySocial login or registration pages, you'll need to enable the "Integrate with JFBConnect" option in the EasySocial settings.
I hope that helps, but if not, please let us know more about what you've configured, if it works with SCLogin and what you're expecting and not seeing.
Thanks,
Alex
