[Plugin: Advertising Manager] How exactly…?

Confused about Advertising Manager. By the way it seems, it should be displaying my ads more than just in the sidebar as a widget. It does not display in my post. I am also currently using the Chitika | Premium plugin which is showing the ad on my post, but nothing that I can see from Advertising Manager.

The “Official Site” throws 503 errors so I can’t really look for answers there.
