Good Afternoon Dear Moodlers,
I was asked by faculty if I could enable Moodle's ability to allow them to grade assignments and allow annotations in the file that students submit in the browser.
I followed the instructions on installing unoconv per this link https://docs.moodle.org/31/en/Installing_unoconv#Ubuntu_16.04_LTS and overcame the issue of "The version of unoconv you have installed is not supported." using the suggestions in this other link https://moodle.org/mod/forum/discuss.php?d=337043. However, when I click on "Grade" assignment I get a "Generating PDF" then a blank page comes up. And it worked fine in my DEV environment that is a mirror of my production.
1. When I go to Site administration > Plugins > Activity modules > Assignment > Feedback plugins > Annotate PDF > and test the path to unoconv I get a message stating "The unoconv path appears to be properly configured.". If I click on "Download the converted pdf test file." it downloads without a problem.
2. When I click on "Test Ghostscript Path" I get a happy face saying "Ghostscritp is working as expected"
What could be the problem? Any suggestions are deeply appreciated.
I'm on Moodle 3.1.2 in a Ubuntu Linux 12.04 box.
Thank you!
DM
