Why am I getting "Your browser does not support iframes" in multiple browsers? I want to display a third party page within my theme and thought an &lt;iframe&gt; should do. However, I added the &lt;iframe&gt; to my basic page, selectingFull HTML but all I'm getting is Your browser does not support iframes with multiple browsers while I can use the iframe on the W3School website just fine. Why is this?

I figured out that it's because I'm using CKEditor.

When editing the page, I had to click on Switch to plain text editor in order to get the iframe to load. CKEditor would convert that HTML into a misleading string of Your browser does not support iframes.
