I am looking for some solution of this issue of iframe

 Refused to display ' in a frame because it set 'X-Frame-Options' to 'sameorigin'.
Failed to load resource: net::ERR_BLOCKED_BY_RESPONSE Refused to display ' in a frame because it set 'X-Frame-Options' to 'sameorigin'.
Failed to load resource: net::ERR_BLOCKED_BY_RESPONSE

FYI both sites are drupal based, if it has any special code. I have already tested same domain and different domain both url for iframe but same error.

As explained on check your x-frame-options value

... they have disallowed loading of the resource in an iframe outside of their domain. So this iframe is not able to display cross domain.
