Problem with embedding iframe on simple pages

I added iframe to a simple page, but nothing happened, so I added “iframe” in the list of “Allowed HTML Elements”. Still nothing, except for the fact that I’m getting my iframe code automatically replaced by the following:

Here are the codes I tried to add, both with the same results:


Any suggestions?

First guess is that some of the attributes on the iframe are also being stripped out. In addition to adding iframe to the list of allowed HTML elements, try adding in all the attributes it needs on the same settings page. Or, just turn off all filtering completely if you don’t think it’ll be a risk.
