Modern web browsers will consult the Access-Control-Allow-Origin header on how to relax the same origin policy for a given page. By default, this setting was disabled starting version 1.5.0SR1 due to security vulnerability concerns. However, CORS can be enabled for certain or all domains by editing the

Save the document using vi's standard commands.
Restart Zoomdata server after making this change and also make sure to clear your browser cache.
