How to show ad space on the header ' right' section ?
 

Hello there ...

I want to put Ads unit on the right at the header ?

How to do it ?

Put whatever code you want in the ad_header_logo template.

... and add any css to the additional.css template to position it exactly where you want it.

sorry , I insert adsense code here 'ad_header_logo template' but doesn't appear ...

Could u guide me how to do step by step

When you make a new google adsense code it can take 10 to 15 minutes, sometimes longer, before the ads actually appear for the first time.

Or if you're using a custom style it may not call that ad location template for some reason... do you know if you're using a heavily customized style?
