I may have figured out the cause. Although all of my other sites are verified this is a new one and that might be why the ads are not showing. I am in the process of verifying the new url. Once verified I will check to see if that resolves the issue. Either way I will follow up.

Catalin, Email was just sent.

Catalin, It’s something to do with the theme. I have tried another publishers ad placement to test my theory also. It is still not working. How can it be Google if it works on 7 other sites I have but will not work on this theme?

I forgot to add the website for someone to review. It is http://www.heatedskillet.com/ – You will notice that none of the ads are serving. There is just a white area. See header, side ads and footer ad.

Also that I have went to admin section Newspaper -> Theme Panel -> AMP -> Header Ads and added set the following:
AD TYPE -> Google Adsense
ADSENSE AD SETTINGS – [ data-ad-client-info ] , [ data-ad-slot-info ] , and set it to responsive.
In the CUSTOM AD section I left it blank.

Still not serving the ads although I have been a google publisher for 6 years. The ad slot is active and test positive else where. Why is not working here. There has to be something I am doing wrong in the theme. It is a fresh theme and I am just trying to get it setup with ads before customizing. I am using the News Magazine demo if that makes any difference. Thanks for the help.

The code that I entered into the header ad is copied straight from the generated ad code that Google provides. I tested it on other sites and it works perfectly. However, when I add it this theme in the admin section Newspaper -> Theme Panel -> Ads -> Your Header Ad and save the entry it does not show the ad. It’s just blank. It’s not an inventory issue there is something causing it not to serve the ad.
