AdSense ads not showing up

You have to wait 10 minutes.

I want to ads from Google Adsense on my site Then I placed the script on side bar

<script type=”text/javascript”><!–
google_ad_client = “pub-lotsofnumbers”;
/* somenameyoudefined */
google_ad_slot = “somenumber”;
google_ad_width = 300;
google_ad_height = 250;
//–>
</script>
<script type=”text/javascript”
src=”https://pagead2.googlesyndication.com/pagead/show_ads.js”&gt;
</script>

but google ads not display on my site . error message display “The page cannot be found” so How can I get these google adsense ads ?

The same thing happened to me. First, check to see if you have more than 3 ads displayed on your site. That could be the issue.
