Facebook/Social Icons not appearing

Facebook/Social Icons not appearing

I am trying to include facebook and soundcloud social icons in my website but I can't seem to use them in the editor (a "blank" element gets placed on the page) nor are they rendered if I put iframe/snippets in.

How can I fix this?

Here is an example of an iframe snippet I would like to use:

  1. <iframe src="https://www.facebook.com/plugins/like.php?href=http%3A%2F%2Ffacebook.com%2Fthatmonkeyband&width=300&layout=standard&action=like&size=small&show_faces=true&share=true&height=80&appId" width="300" height="80" style="border:none;overflow:hidden" scrolling="no" frameborder="0" allowTransparency="true"></iframe>
