For the website in Chapter 8, I could get either User Profile button or the Video Upload work but not both. Either will work (and it seems like which ever is invoked first will work). The error message from Developer Tools is consistently like below:

XMLHttpRequest cannot load https://* No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin '' is therefore not allowed access. The response had HTTP status code 403.

Anyone else has same issue? Any idea what went wrong here? Thanks
