Adsense right side works everywhere but homepage – anyone ever run into this?

It works here: https://energyanalysis.org/2008/07/01/gasoline-prices-finally-slipping-first-time-since-march-08/

It works here https://energyanalysis.org/archives/

But not here (on the homepage) for some reason: https://energyanalysis.org/

Why is this problem happening?

This template came with the UBD block ad plugin, which uses a widget called “affiliates”, and I also use adsense manager plugin. Both of them are not working in the right sidebar on the homepage.
