I tried activating the "request email" option when it cannot be retrieved from the social container, and I also activated the option to try to unite to an existing user account when the email is the same as that of an existing account.
Well after connecting my account with facebook and google, I now tried logging in using my twitter account. I received the popup "your email could not be retrieved from twitter, please insert it here". I typed in my email but got an error message:
"This email is already used by another account".
And I'm stuck there! If I don't enter in a different email address, I can't login and I can't logout, I'm stuck on the popup!
How come the plugin doesn't unite my information from the twitter account with my existing account?
