Cross-Origin request blocked

Occasionally when you first enable SSL on your server in your browser's console you might notice the follwoing error:

Cross-Origin-request blocked: the Same Origin Policy disallows reading the remote resource at https://www.[YOUR_DOMAIN].net/index.php?option=com_docman&controller=scheduler. (Reason: CORS-header 'Access-Control-Allow-Origin' missing).

This is usually because some requests are made using SSL while others are not using SSL, this makes the Same Origin Policy error kick in.

This solution to this problem is very straight forward, simply change the parameter for Force HTTPS under your global configuration's Server tab (System > Global Configuration > Server > Server Settings) to Entire site.
