Social Login Plugins
I think the social login plugin doesn't create wpForo profile for new registered user. Try other social login plugins and check new registered users, because the old users have already incorrectly created in database.
Also want to let you know that next wForo version comes with Facebook login button (in a few days). If the Facebook is enough for you I'd recommend deactivate your social login plugin. We'll also add Google+ and Twitter login in future releases.
Hi, how to setting, media social login ? so people didn't need register first to give reply post. Thanks.
