How to enable CORS in your hosting account
If you are a developer and need CORS enabled to run your app you can enable it by adding the following lines in the .htaccess file in your hosting account.
<IfModule mod_headers.c>
Header set Access-Control-Allow-Origin "*"
</IfModule>
Other option is also enable the headers in your script if you are using PHP, for example:
<?php
header("Access-Control-Allow-Headers: Authorization, Content-Type");
header("Access-Control-Allow-Origin: *");
header('content-type: application/json; charset=utf-8');
?>
