Chess.com Facebook App

I've just started using the Facebook application for chess.com. Everytime I try to write a message, a pop-up appears saying first:

"An error occurred during AJAX Response parsing.



The error response will appear in a new popup."

This happens, and the new pop-up tells me that

"Permission denied to get property Window.document

on line number 169

in file http://fbapp.chess.com/assets/js/_core/post.js"

Any ideas? It seems a bit rude not to reply to messages.

First take permission from chess.com

dude, you do not have to post in every single topic on chess.com. Take a break.

Did this ever get solved? I'm trying out Chess Mentor, but everytime I do the last move in a lesson I get this AJAX parsing error. I've tried it in Firefox and Chrome, have logged out, cleared all cookies etc. then tried again, but the problem persists. What should I do?
