Comment on SEO AdSense WordPress Theme by SEO Dave.
If your code looks like that, should work. Must be exactly like the AdSense code above other than your AdSense pub number and the ad slot which are unique to each ad unit in your account.
If you followed the exact instructions here: http://stallion-theme.co.uk/google-adsense-responsive-ad-unit-beta-stallion-responsive-wordpress-theme-integration/ it works.
It’s important exact instructions are followed when you use the AdSense responsive code.
