Everything has been installed perfectly, and I have tested it out extensively. Users are able to register with the new social buttons. Then the newly registered OneAll users can go into their control panel and link other social media accounts. Unfortunately, users that were already registered, previous to us installing this extension, are unable to link their social accounts. The window opens, you login to the service, and then it closes the window... but there's no green check mark added. And when you go to signin with the service you just tried to connect, it creates a brand new account.
So users that register with the extension can use the extension to link further services to their account, but members that did not register with the extension are unable to add social links.
Is there some code that I need to include on the website?
