I use Adsense-Deluxe plug-in on my Wordpress installation. However, I am having problem with a blank white space after the 3rd Adsense ad. Basically, I am enclosing my Adsense ad within a <span> but I still see a blank space after the 3rd ad. The space is not supposed to be there since Adsense-Deluxe is not supposed to display Adsense ad after the 3rd ad. An example of my problem is here.
I'm having the same issue. It used to work fine. The 4th ad never appeared, but now I have a blank space on the 4th and subsequent posts. Not sure what changed.
