I have an implementation of uploadify running on top of a PHP application. It was working just fine on my test machine. However, I just uploaded it on to my production machine and it is failing. Uploadify correctly replaces the input field and presents the button. However, when the button is clicked nothing happens. It completely fails to open the file browser. No error. Just quiet fail. Any ideas what could be going wrong here? Something in the php.ini? A mod I haven't downloaded? I'm at a loss.
Edit: When I follow the links through and load the uploadify.swf flash directly it works fine. The button shows, click on it and the file browser appears. But when I load it in the web page, it doesn't work. The button shows, but clicking on it yields nothing.
