Score Could Not Be Submitted - Fresh Install On New Board
 

I just installed the latest version of the arcade on the latest version of vBulletin. Both installs are fresh, yet when I try and play a game (ANY of the 6 or so games that come preinstalled), when I try and submit the score it tells me there was "An error submitting the score" and it doesn't post the score. Any ideas?

I read that if you are using something other than index.php as your forum home page, it won't work. I am in fact using forum.php as the forum home page, however I am not using any kind of portal (it's just a regular splash page). I found the code that said to add if you are using a portal, but it's just a regular HTML page (although saved as index.php), so where should I add this code to get it to work?
