Lately I have been getting this message when I tried to replay to a pm message on my cell phone. I tried to hit reply to a message it just shows that message for a second and sends me back to the front page of the forums. I did a quick check around it looks like its a problem is with the firewall on the server or a bug that's only present when running on a windows based server. I also tested my phone on a different php message board with no problems.
