Somehow recently my checkout_success page has decided to be blank. After the customer clicks the button to process the checkout_process page loads and after a few seconds redirects to the checkout_success page, however it's completely blank. I have no idea what could have caused this, I haven't made any changes whatsoever to this page or any other page within the installation.
Totally bewildered with this one. The order does process via (AIM Authorize.net) and the email confirmation still goes out thank goodness, but I'm sure the customer is very confused when they get nothing but a blank page after the order goes through. Also, don't laugh, this installation is version 1.2.5, php version 4.3.10, MySQL 4.1.22.
