I'm using your module for login and it's working fine. For registered users I'm using only social login. I also have client users that can not use social login but can login only via joomla created user. I want to use joomla login form only for my clients but there are also social buttons in login form.
So, how to remove social buttons from login form and not login module.
In the JFBConnect -> Configuration -> General tab, there is an option for "Integrate into Joomla Login". Disable that setting, and the buttons won't show.
I hope that helps, but if you need anything else, just let me know.
