What do you mean page? A new page in browser? Wifi turned on? Is your internet working on other devices?

When I try to get to apple store or try to get an app downloaded I get a pop screen (can not open page because address is invalid).

Wifi is fine, I am able to browse the net, pop blocker is off, only when I hit the apple store button.
