How to Remove the Adsense Warning...
Your AdSense account is enabled only to show ads on YouTube. If you want to show ads on a different site, you'll need to provide us with the URL of the site you want to monetize.
You get this warning because your Adsense for content ads are not approved. Youtube Adsense is a Hosted Adsense Account. Blogger Adsense is also considered a Hosted Adsense Account.
In order to get Content Ad Approval you need to first build and then provide a TLD - Top Level Domain - Website with quality content and not a .blogspot. URL. Once you are ready to apply for Adsense you place the Adsense code in the *head* section of your Website or Page Templates.
Make sure you follow and comply with all the Adsense Program Policy Guidelines to prevent your account from being rejected or banned.
