For about a month, the adsense clicks and impressions have stopped showing up in my google account, and its been driving me batty tryig to figure out what it was.

I finally found it last night, a tiny setting in the drupal google analytics module in advanced settings where is says "Track AdSense ads - If checked, your AdSense ads will be tracked in your Google Analytics account."

I had this setting switched on, but as the account I was tracking was the primary analytics/adsense account, it does not need to be on, and in fact, stopped the adsense statistics from coming through, that is only needed for secondary accounts. Sigh.

Maybe that will help someone else in the future. Now I can see the click again on www.dirtbike.ws w00t!
