Well I never figured it out myself. I had a momentary problem myself on Gizmos site several months ago for a few days,but then it just started to work again.
But you do know that Firefox hides the red x error that you would get with IE.
Some where in the current firefox version is a way to unhide it I recall. It may just be the error console.
I forgot your url to try. Since I use firefox.
Can't seem to find a post with your site.
