my google and altervista is active but don't work

after clicking the email redirecting to adsense, this is the message:

Il tuo account AdSense ti permette solo di pubblicare annunci su YouTube. Se desideri pubblicare annunci su un altro sito, devi indicarci l'URL del sito da monetizzare. Ulteriori informazioni

It's a known AdSense issue, it doesn't allow to associate your AdSense account to AlterVista if you use it to publish advertisements on YouTube. We can't do anything about that, you should ask AdSense to remove the limit on your account.
