One Of My Ads Isn't Showing Up--Why Not?

I just checked my Adsense report, and I've had about 2,000 visitors today, but my leaderboard on top only has 9 impressions counted. My other ads all have 1,800+. The weird thing is, when I look at my site, the leaderboard always shows up. Why isn't it being counted?

 

You better generate Adsense code once again. It's probably corrupted.

Use channels.

 

yeah, i kind of have the same problem. the ads work fine on all the indivdual pages, but i get no on my homepage. relief ad on the right. i took them off for the time being and try again in the morning.

all my other sites are fine

 

it happened to me once on only my forum, i fixed it by restarting my computer lol, it was weird, it was just on my computer too :/

 

Your ads become white board?

 

No, they showed up on every computer I've used today, they just didn't register impressions on AdSense. I reinstalled the code, and now it is working fine.

 

Probably PSA's.. or else you have choosed a solid color to fill up the space..
