I am using [url removed, login to view] wordpress plugin to allow users to login from [url removed, login to view] page.
You can test on [url removed, login to view] and click the Login option in menu to test user account creation. It will work fine from menu Login link.
The problem is when I have users login from checkout view. To test this, add 1 product to cart, then press checkout, you will see login step. IF you click any of these social media login buttons you will see nothing happens after you connect your account.
What should happen is that menu updates to show Logout, and user proceeds to About Step.
The company OneAll has support team, and they have provided me advice to fix the problem. Look here
