The error reporting service is turned on. My puzzle is that the BlueSkyMusic site that I loaded for trial works perfectly. When I create the product pages for my site, they work perfectly until I insert the add to cart button. I can see the page and all my products on the localhost test server before I insert the button. After I insert the button, the page is blank and there is no source code if you view the source code from the browser. I am certain it is a simple fix with a setting but I cannot narrow it down.
