There are a bunch of warnings, but this is the only error:
Error: uncaught exception: [Exception... "Component returned failure code: 0x805e000a [nsIXMLHttpRequest.open]" nsresult: "0x805e000a (<unknown>)" location: "JS frame :: http://www.playmage.com/js/dw.js?46 :: sendRequest :: line 1" data: no]
Thanks for helping with this.
