Adsense Channel Monitoring

Hey guys, so I've recently tried to create some adsense website but there is problem I have right now when trying to track how many page impressions and clicks I'm getting. Right now on my site, there are google ads so I'm not banned or suspended but when I go on my adsense account my channel is no longer under the "Adsense for Content" section. Right now this is really frustrating because I feel that my site is not going against the TOS. Can someone walk me through how to create a new channel? I did:

-create a custom channel
-create an ad unit
-put ad unit in this custom channel
-put the ad unit code on my site using the "easy adsense" plugin

Thanks!

Btw, does anyone have a better adsense plugin or is this the best one? Made sure that under donations I put "0", but is there anything else I should be aware of?

EDIT: so I went on the "Site Diagnostics" tab and found that my url "http://www.domainname.com/hello-world/" is blocked. I think its because it no longer exists, but I don't know how to correct this. Also could this one blocked url really be the cause of my channels not showing. (I have a custom channel and url channel for this website)
