I shared this problem on a new voucherpress install, v1.2.
I had left a couple of ‘edit’ boxes deliberately blank when creating my first voucher, and wondered if this might be confusing the PDF creation process.
I deleted the voucher & reset the database. Then re-created a second voucher. By entering some text – in my case ‘****’ which did little cosmetic damage to my voucher, into the previously blank fields, everything worked!
So, if you have any ‘blank’ editable fields on your voucher, this could be a workaround. Hope this helps, K.
