I have a Drupal 7 site and a Facebook page. I have created a tab on the Facebook page which should allow me to display a page from my Drupal site within the tab. On Microsoft Edge I get a warning saying that the site doesn't allow iframes, on all other browsers I have tried nothing displays at all.
I have enabled Security Kit, disabled X-XSS-Protection, allowed cross-site request from https://facebook.com and disabled X-Frame-Options.
I enabled the iFrame entity module and allowed nodes to be iFramed.
And I have put
$conf['x_frame_options'] = ''; in my settings.php.
I still am unable to display a node from my site on an iframe.
How do I get around this?
