I have been having the same problem since Saturday. It's getting very annoying to see, to ad boxes and nothing else on the page. It only seems to do when I am working on my site. If you click the website manager it goes straight to the stupid ads boxes and no page of mine!!! Grrrrrr!!!! I'm getting frustrated too!!
I am also having this problem when updating my site. Sure I have a free site, but this type of advertising
is destructive. I've been struggling with this problem for at least 5 days or more. I have tried refresh/reload several times unsuccessfully. It's just this one ad that is causing the problems.
