This (Joomla) error is due to the fact that you have set the User Registration process to wait for the User Activation.
since the User has not been activated yet, it cannot login.
We suggest setting JFBC to bypass the User Activation process, when a user registers to the website with his FB Account, since FB has already done the activation (validation of the email), and it should be OK to trust their validation.
As for the 500 error, it seems to be happening only with IE9m so there must be some JS error hidden somewhere.
