Coner didn't copy all pages, gave menu error message

I tried cloning the main site anvoy.com to a new site anvoy.com/anvoy2. There were a couple of error messages about not being able to copy menu items. The home page of anvoy.com/anvoy2 looks fine. But http://anvoy.com/business-simulation-for-youth/ did not copy over to http://anvoy.com/anvoy2/business-simulation-for-youth/. Other pages didn't copy over either.
