Hey admin,
after Update to latest Version of VM2 and OPC, I've got another emty page error - this time it appears when going to cart/checkout.
For example: http://matthewgraye.com/index.php/vinyl ... etail.html
Just pick one Product and go to the cart/checkout. Now blank Page appears.
I'd be very glad if you can help - I'll give you Admin-access if needed!
