DNN 7.2.2 as an extranet

Our client wants to utilize DNN Admin Site Log feature. She likes the idea of seeing the frequency of registered users, etc which she says she can't get via Google Analytics.

I have gone to the Host Settings page and set "Site Log History" to 60 days. I have also gone to the Admin Site Settings page, under the Host Settings section, and changed the "Site Log History (Days)" setting to 60 days. I am getting "No records were found" when I visit the Admin Site Log page and try to generate any reports, regardless of date range, etc. Is there something that I'm missing?
