I've been stuck in Atahualpa 3.5.1 because I want to have an Adsense ad show up after the 3rd post in my site (I believe that was called In the Loop way back then.
I'd like to upgrade to 3.7.3 if I can figure out a way to do that. I saw something in one of the posts about using the INDEX php, but I don't know where to try it there.
Is it possible? If so, how and where do I place the Adsense code?
I still love this theme even if I'm not a programming whiz.
