Try update your core Facebook API Kit with the latest version, Internal Error 500 is more than likly one of the following:

Facebook's Rest server is experiencing issues with server load. Your requests are invalid, thus the need to update your library.

If the above does not resolve the situation try ask in the Facebook Developers Forum.
