I am currently running two arastta stores, and both are up to date.

On one, after generating an invoice, I can generate the PDF Invoice but for some reason it makes 2 pages where the second is blank. Minor issue. I just don't print it.

On the second site, I generate the invoice and when I try to generate the PDF Invoice, I am getting this error:
