Facebook page plugin not appearing within custom page block

[JTrollerb123]

Hi, I've tried inserting both versions of the code (javascript and iframe) from Facebook Developers portal to include the Page Plugin as a block within the site.  But either way when I do it, this is what I receive - A blank widget space which does show the same dimensions for what I selected in the settings (180 width x 220 height).  Anyone else have this issue?  Any ideas?

Thanks!
