Ad Widget isn't working with google adsense or media.net

You should have access to see this here. I enter the ad sharing code as described in this widget but it isn't showing up. Also, how can I know the size of the right rail or other ad space sizes since this is not described with the widget?

You can see it doesn't display on the right on pages. Its blank. I can't share too much since this is public but I think you have access to get into the system.
