On one of my sites, adsense does not show up. I have 3 adblocks and 1 adblock is a 336x280 one that is incorporated into the text which shows up fine, but the two other ones(both 160x600) in the sidebar show up as nothing, but a solid blue color(which is their background color). the weird thing is when i add a "www." in front of my site in the url, the ads appear, but they are showing the kinds of ads that are totally irrelevant. I know there are more ads that can show because this niche is full of ads, but why arent they showing?
