I have a couple wordpress blogs. On each one, I designed it to display an adsense banner at the end of each post. My main page displays 5+ posts, so due to the adsense limit the first 3 posts would display the ad banner, and the remaining would not display anything. Just recently this happened, the first 3 posts still display fine, but the fourth and sometimes fifth one, instead of showing nothing, displays 'The webpage cannot be found' in the banner spot. The remaining posts display nothing where the adsense banner would appear. I posted a message on the adsense forums, but I was curious if anyone here may have run into this and knows the cause.
