I have just got Smith cart 5.68 working and it is looking ok. On DNN 7.0.4
he problem is when I open an order in "Manage Order" and click "Print Order" I get "A critical error has occurred. The number of columns in PdfPTable constructor must be greater than zero"
What should I do here?

I had left them the same initially but when I deleted them and re added it works.
