Uncaught Error: Parent origin mismatch: null, file://

I copy pasted the code found at ampbyexample and all I've got is this error with an empty page.

How do I fix this so the page loads up?

Did you just try to drag and drop the HTML file into the browser? I did that and got the same error but then when I put it into my MAMP htdocs folder, it loaded perfectly fine with no errors from localhost:<Apache port>/<path to file>. Hope this helps.
