Increase in authorization permission errors – Webmaster tools

I recently installed Facebook Connect on a site I manage and just noticed that there is a huge increase in permission errors in my Webmasters account. Can someone help me figure this out?

These is an example of one of the urls that have problems. There are 3000 more errors
