Yep, went to a blank page.
It acts as if some critical files have been tampered with or deleted from your site.
If it were me, but it’s not, however if it were me 
then, if you have not modified your CS-Cart core program files, I would start by re-uploading the cart files from your original download.
Just be sure that you do not overwrite your config files or modified skins!
I had this happen one one order. It seemed like it was only with that specific product combination. no idea. Never happened again.
