We have a separate intranet site that iframes a specific Sharepoint page. It gives the following error:
To help protect the security of information you enter into this website, the publisher of this content does not allow it to be displayed in a frame.
I've read that it's possible to allow iframing for specific pages. How exactly do you modify a specific page in sharepoint 2013? Can this be done without modifying the master page? If so, how?
