I hope this is the right place to post this. If not, I apologize in advance.

I am able to get adsense ads to show on other pages but for some reason I cannot get the adsense ads to show up on my bookmarking website homepage.

Please have a look: http://www.bookmarkloop.com

This is a Pligg website. You see that I have placed the code on the bottom right of the right sidebar and in the middle of the content on the home page. For whatever reason nothing shows up and this was placed on there two days ago...

Any help would be great!
