First off, BT Login module is not our extension.
If you're saying there is a conflict between BTLogin and SCLogin, you will need to provide more information. What "other buttons" are you referring to? The SCLogin module does not have social login functionality on it's own, you'll need to have JFBConnect purchased/installed for social logins. By itself, the SCLogin module is an improved login module with better customization and styling options over the standard Joomla login module.
