I run a poster printing center at a university and we use WordPress with Formidable Forms. My order form includes the ability to attach files to be printed. I have a customer that used Cairo to generate his poster as a PDF:

Interestingly, when the file is attached to the order form it breaks the file uploader and the form fails. I decided to take his PDF in Acrobat Pro and print (not save) it to a new PDF which became the below and it uploads perfectly file attached to the order form.

Does Cairo support exporting to a newer PDF version (at least 1.6)? I curious if the issue is strictly how Cairo encode the PDF or if it's the PDF version that Cairo generates that is tripping up the file uploader in Formidable Forms.
