Cross Origin Request Blocked Error - how to resolve?
Followed steps, when sending ajax request error "Cross-Origin Request Blocked" is thrown with console suggesting that "CORS header ‘Access-Control-Allow-Origin’ is missing."

I typically have gotten that before for 2 reasons.
If you are requesting an "http://" instead of an "https://"
If you are trying to pull something from another website that doesn't allow your jQuery/AJAX to pull the content.
