Problem with redirect to paypal page

[francota]

Hello to everyone
I have a problem, after confirm the buying the system shows me the page "wait you will redirect to paypal page", but after this i have just blank page.
On my hosting i have a redirect second level domain like this:
xxxxx.it >>>>xxxx.namehosting.it
All woks perfect when i dont use the redirect, but when i use redirect with cloak i have that problem

Sorry for my englih i am italian
Thanks
