In another game I was in, I had a similar problem to the one you are having here. In that game, if I recall correctly, the actual game client was one turn ahead of the website. It was on turn 18, but the website was on turn 17. 2h files would get rejected for being the wrong turn number, and when it finally hosted, everyone staled. You may want to get llamabeast to take a look before trying to continue. When I contacted him, and explained what was going on, he seemed to know exactly what was going on and was able to fix it quickly.
Here is the thread.
