问题 I am using google maps api and on the page I have this <link type="text/css" rel="stylesheet" href="https://fonts.googleapis.com/css?family=Roboto:300,400,500"> now, because of this, as you can see in this link https://fonts.googleapis.com/css?family=Roboto:300,400,500 there are font files - included by url, and AFA i understand it causes the problem. In firebug it shows Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://themes
