[cairo] [BUG] PDF Error with Formidable Forms File Uploader

[Hawley, Ronald]

Hello,

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.

Thanks,
Ron
