simple WWW code works in editor but not on server

var www;
var cube:GameObject;
function Start() {
www = new WWW(“”);
yield www;
if(www.text == “hello”){
cube.renderer.material.color =;
cube.renderer.material.color =;


The php code resides in the same directory on the server and the php code simply echo’s “hello” to the client.
There is a crossdomain.xml file in the root and in the local directory where the unity file, html page, and php files live.
Any help is appreciated.

Test the server by hitting that url with Firefox or something. Put a Debug.Log(www.text) in to see what that is coming in as.

OK. The project was originally a Unity 2.6 project and was upgraded. It works fine from scratch.
