hey,

order of parameters doesn't count. Do you test it on localhost or external (public available host)?

Google tries do match ads for your content, if your host is not accessible sometimes there are no ads, just empty content. Google provide a mechanism for that: you can provide "alternate_url" parameter, and when there are no ads availalbe it loads content from specified url.

Does ads load correctly when pasting code generated by google adsense admin panel? It will answer the question where is the problem.

Thanks a lot, man. It is working fine now. I appreciate your help.

So i put the above script on a rb file then put
<%= ad_unit(:leader_board, "your-adsense-id" %>
where i want it?
