AdSense Display Bug: Showing Wrong Size Ad

Medium Rectangle in a Leaderboard Spot

[martinibuster]

I'm seeing a 300x250 Rectangle (image ads and text ads) popping out of 728x90 Leaderboard spot. The ad is being fed via DoubleClick into the wrong ad size, causing the ad to pop out and spill down into the content, breaking the template.

Banning the URL doesn't help. Google/Doubleclick feeds another ad that's the wrong size. The bug shows up in IE8 and IE6, but not FF.

Anyone ever see something like this?

I've seen some wrong sized font on my old adsense code, but no wrong sized ads.

Anyone ever see something like this?

For the past few weeks there have been various ads on a UK TV guide channel doing a similar thing...a bit like Jaws coming at Marty McFly in the town square in Back To The Future...quite impressive in FF HOWEVER it does cover a lot of the guide but does have an X top right.

Are we referring to the same thng?

The first time I saw it I was very annoyed therefore I can't imagine what Joe Public thinks about it.

I think it's doubleclick code. I heard back from AdSense and they say it's CSS that is affecting it. Even though nothing has changed on my site, they say it's my site that's bugging it out. Additionally, the Google code is not being styled either by a span or any other way.

So I suspect it's a bug on google's part.

Once in a while, on a new or reworked page, an AdSense block will show up in an I-frame I use for other stuff.

It's like AdSense somehow gets confused.

Looks really odd because it's trying to show a 300x250 adblock in a 120x600 I-frame. (there is no AdSense on the page actually being called in the I-frame)

This is usually very short lived, a couple reloads of the page and AdSense seems to get straightened out.

I don't use any CSS on my pages.

Ok, figured it out. I installed a third party tell a friend/social media JavaScript gadget on my site and that's what was causing the AdSense code to misfire. Everything was working fine until last week, so I still suspect that whatever went wrong it's something on Google's side where their code changed. AdSense displayed fine up until last week.
