In the cases where the email address of a user is already registered in the system, when they use either FB Connect or TW Connect to Sign in the system doesn't give any message back. In FB's case: shows the permissions window, allows access and the window disappears, nothing else is done. In TW's case, once the user type's his email address twice, deloads the page without giving any message. Can you please clarify where the problem is? Thanks for your help.
