Ok, now I got to the next point. I follow your directions and now I can access pay pal and sign as guest but when I press continue button this message appears "Oops! Google Chrome could not connect to localhost" and this address in address bar "http://localhost/pp_confirm.php?token=EC-7M2711531H345080B&PayerID=SP82RQEE5WMAU". Looks like can not access the pp_confirm.php page. please advice.
