On the sidebar of my site, I have inserted a Facebook Likebox. If you're not familiar with what this is, here's a pic of it...
I've inserted this using Appearance > Widgets > Text.
My problem is, when someone IS a member of FB, AND IS logged into FB, they see this box. When someone is NOT a member of FB, or is NOT logged into FB, they see only a white box, the same size as the Facebook Likebox. In this case, W=240, H=370.
Is there a way to set this up so that if there is something to display, it gets displayed, else, if there is nothing, the W and H get set to zero?
I'm not seeing how this might be done, yet.
