web publicity does not appear

Hi.
First of all indicate that I am a newbie, I used to use the adsense plugin that Google currently disabled and I found this one that seems to have to go great but I think it is not configured …

we want to put the publicity in a particular part of the footer and in specific places of pages that we have reserved for publicity … from what we see, it seems that Google now wants to make it show 2-3 styles that they have configured and I don’t know if the plugin can help us.

I think we have well configured, but nothing appears … leave blank spaces where publicity should go, but nothing is shown, only spaces

Thanks and sorry for the inconvenience
