Hi Mary,
End of the day here again...and time for another cup of coffee.
I thought that might be the case for Mount Orange. Thanks for the confirmation.
I went and looked at the QA Test Directions for this (https://tracker.moodle.org/browse/MDLQA-9790) and they had to do "some work" on the code for it to get it to work and eventually pass QA Testing. The test directions only checked conversion/grading for PDF (which works) and DOC files (which doen't work), which for me doesn't really matter at the moment as I've managed to break my test site.
I tested an online text submission of about 1800 words, and the grading page would not finish loading. After waiting a while (another cup of coffee) I restarted my web service to get pages to working again. That student was permanently broken. Creating a new assignment, submitting other documents, no matter what, Moodle always complained the file could not be created as it was a duplicate. I deleted the assignment and created new ones. Same problem with that broken student. I even deleted the student from the site and got the same results when I re-enrolled him.
I searched through the table mdl_files and there were NO duplicates of what was being created. Eventually, I went in and started deleting items from the mdl_files table and still could not get the grade page for that student to load. Now, I seem to have removed one entry too many and cannot even get anything to happen when I click on "Download the converted pdf test file" in the administration area for Annotate PDF. It at least used to given me a broken pdf page in Firefox.
Tomorrow, I think I really will haul out another old computer and set up a Ubuntu server to see if I have a better result with it.
