Load denied by X-Frame-Options: does not permit cross-origin framing in Magento 2

Step 1 : Open magentoroot/app/etc/env.php 

Step 2 : Find -> 'x-frame-options' => 'SAMEORIGIN',

Step 3 : Replace -> 'x-frame-options' => 'GOFORIT',

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource

Write following code into cross-origin's .htaccess file

<IfModule mod_headers.c>
    Header set Access-Control-Allow-Origin "*"
</IfModule>

Example:

• You open "http://example.com" (here you see the cross-origin error of http://abc.com)
• Open .htaccess of abc.com and paste above code.

Ex 2 .

in php file : header('Access-Control-Allow-Origin: *');
