OK, I was getting this again on 2 of my sites, one was thomasandfriends.info it was saying 99 times out of 100 'ads not found on ' and no URL. The other 1 time it said nothing found on http://thomasandfriends.info which of course is wrong, they are showing. However, when I changed the site URL in my settings to thomasandfriends.info/index.php all of a sudden it would validate just fine. Of course that's no good, because the Pagerank is on the plain URL. So I tried back to thomasandfriends.info on it's own, and same thing, no ads found on blank. So I changed the URL in settings again, to thomasandfriends.info/? which brings up the page with rank anyways, and it validates fine. Something not quite right with the validator maybe?.. Who knows. Anyways, if you're having trouble validating with just a plain http://xxxx.com url, try putting http://xxxx.com/? or your index file or whatever instead, it seems to validate better that way.
I'm getting an error on all my big ads I just added to http://www.wrestlingpod.com/wrestling-news/ They are supposed to appear above the main graphic and my Javascript window says 'b had no properties' in Google's show_ads.js. However, other adsense code works elsewhere on the page just fine. Odd. Nevermind. I got mine to work. Formatting issue or some sort of conflict. Fixed though.
