Adsense not appearing on my page

This blog is already a year old but I just recently changed the domain name. So since having a domain name, I also changed the layout/template, the Feeds and Adsense accounts. But when I put my Adsense code, the ads wasn't showing up on my page. I thought that it's because it's using a new domain. I waited for couple of days to see the same thing. I also sent an email to Google Adsense support but didn't hear anything back from them. I seek for G's search engine's help and still nothing helped. Then, I just decided to go search answer at Adsense Help again coz it's almost impossible that there weren't any solution for this kind of problem, and if there is, they should have it.

I looked hard for the solution, then I found this Why aren't ads appearing on my site? article. Actually, I found it again but I missed what I needed to look for the last time. So, among all those possible problems and solutions listed on that page, here is the one that I had and did:

Do you have too many ad units on your site?
Our policies permit publishers to place the following number of ads on a webpage:

* Up to three ad units
* Up to three link units
* Up to two search boxes

I didn't realized that I already had more than THREE Ad Units in my page (actually, I had five). So, I deleted some and left two of them. I still have the search box and link units too. And that definitely solved my problem. Of course, thanks to Adsense Help!

So, if you'll have problem with your Ads, just look for it in Adsense Help and you'll surely gonna find it. Read everything so that you won't miss anything.
