Adsense Banned only from one folder on my site?

I can’t seem to figure out why no adsense will show up here:
I’ve checked the code and it seems right.

But a little background…
This forum was overrun by prn spammers for a month or so. I got a programmer to help clean it up and put it back online after removing it for a month or so. Do you think think google banned just this folder from adsense? If so, what can I do to get it back in?

It’s true that no ads displays for me too.
You could contact adsense directly and state your problem, I think that’s the only way to revert a ban of a folder.
