Main Page Not Being Protected, All others are?

As the title says, It appears that my main page (index) is not being protected however the other pages are.
You can view this at:

They should be re-directed to the subscription page, which I've customized to say something different about restricted access as they have not been verified yet.
Does anyone know of a solution to this problem?
Thanks
