We are running Moodle 3.3 and are loving the PDF feedback tool. Although Unoconv has worked for all of our Doc, pdf, ppt, etc files. We are now using the Google converter for these.
Unfortunately when a student submits a photograph in the form of a jpg or png, the converter runs for a moment and then returns a blank page. This is true of pictures and text files.
I've tried runing unoconv from the server command line on these same files and it works perfectly. It only seems to have trouble in the PDF Feedback tool in Moodle.
Anyone else running into this?
