Over the course of the past few months, I have received blank sales orders.. no product info, no customer details .. nothing ....

I have tested this on various platforms and have not been able to reproduce the errors...when I cancel the order before payment.. I am always still sent an order with all product info etc....

I have no idea why I am now receiving completely black sales orders..

I am using version 8.0.16

Anyone seen this before ? 

Cheers
