Adsense robots.txt Error to sites and Blogger

Today, I got an email from google adsense,which saying
” While reviewing your ad implementation, we noticed that your robots.txt file is currently preventing our AdSense crawler from reaching a significant number of pages with ads in your account.” I have searched for this problem, and found a lot people got this mail.Then , I check my sites’ robots.txt, and add the
“User-agent: Mediapartners-Google
” which the adsense suggested. Most of my sites are wordpress and blogger, my robots.txt isn’t blocking any bots on pages where ads are displayed. just like this site:, you can visit, and there is nothing. For blogger, and I have checked the blogger robots.txt, just browse,what you see??

User-agent: Mediapartners-Google

User-agent: *
Disallow: /search
Noindex: /feedReaderJson

So, there is nothing wrong with these robots.txt. I think this mail have send to all of us.
you can use edit the blogger robots.txt if you have added sitemap to google in google webmater center.

or you can try adding an entry in the blogger html like this:
