I got through the ordering process for Shutterfly, but when I got to the payment page, it went blank and just sat there. I tried it again, and the same thing happened.
Shutterfly has updated their website recently, when removed the page PSE logged into. We are working with them currently to get this page back up.
I logged in without a problem. It was when I got to the submit order stage that things went blank.
That's strange, the log in page should be gone to. You probably just had a cached version, but when new information was required, that is when things when wrong.
