Won't upload, error says PDF has different size pages, but it doesn't
I keep trying to upload a PDF, it processes 100% then reads that there are differing size pages within the PDF and won't accept it. The template was directly taken from Lulu, pages are to bleed, everything is 300dpi, not sure what else to do.
Thanks in advance for your suggestions.
