Hello,
I'm afraid that you don't understand the question. The embedded iframes used to work normally on WP 4.6.1. but after the update to Wordpress 4.7 it stopped working.
I've tried to copy-paste the code in this forum but don't know how. You may check the codes at the inc.com links that I gave you.
All embedded iframe videos originating from http://www.inc.com using / generated by Kaltura, stopped working.
I have no problems displaying embedded iframe vids from other sources like Youtube, Vimeo, etc. I guess there are some codes from http://www.inc.com/js/kaltura/moreViewOptions.js line line 12 are conflicting with new wordpress 4.7.
Can I send you an IM so I can give you the login credentials to my website. Please provide me your email.
