I login to adsense and created an ad unit, copy the code and put it in text widgets. and it shows blank on my website.
But when I go back to my adsense account . it still show "place the ad code" button.I made a screenshot.
you can see there is a mark before "You've successfully created an ad unit" but none before the "Place the ad code on www...".
Have I set the ad code right? I don't know if I do the right thing why there is no mark and the "place the ad code"is still there?
What should I do if I am wrong? Need all your guys help. Thanks!
