I need a Google Adsense expert

We can't find the page you're looking for. Check the URL and try again.
That's what happens when I click the ad setting preview.
when I first started this endeavor and I added my site as ourclicko.com but I was directed to add a redirect to my domain name and as a result Adsense can't find ourclicko.com. Should I have entered clickosites.com instead?
