I think something wrong with my template or PHP code the Adsense never show or it shows Charity ads http://www.bangkokevents.net/ Do you see anything wrong with it?
I can see normal ads on your inner pages, but indeed not on your mainpage. Most likely the reason is that Google cannot figure out what that page is about, too many different articles, and therefore displays the charity ads. But there is nothing wrong with ur site, besides that it covers too many unrelated subjects for Adsense to show ads.
