Welcome to the Q&A Forum

I'm assuming you mean the SEOMoz on page report card? This issue usually seems to be related to not using a valid URL or being some sort of cookie issue (pushing the button twice) and clears itself up. http://www.seomoz.org/q/why-am-i-getting-an-access-error-when-creating-my-first-campaign http://www.seomoz.org/q/onpage-report-check https://twitter.com/fkaasgaard/status/258555937231630336 So make sure you're using a valid URL - if you know you are, clear the cache & cookies, reboot the browser and relogin to Moz. Should clear itself.
