Hey Sergey,
Thanks for the prompt reply.
I used the "Advanced uploading of files" for the assignment; it is set so that the students can upload only one file. Cron logs appear to be normal. At the end, it shows:
<!--StartFragment-->Cron script completed correctly
Execution took 1.916916 seconds
I meant "similarity score" when I said "percentage error." My apologies for the confusion.
The similarity score is showing up now, but it is not picking up plagiarized posts. I tested it by turning in a Wikipedia article under a "fake" student's account and it shows a similarity score of 0% when I log-in as the instructor. When I click on the "0%", it says "no plagiarism have been detected OR check up was not performed yet" but the article was clearly plagiarized from Wikipedia.
How should I proceed from here?
Much appreciated,
Yandi
