We are currently seeing an issue with the Turnitin plagiarism checker, where students are uploading assignments and receiving the error "Turnitin has returned an error with your submission: The file failed to upload."

The error only means that there has been a delay in sending your assignment to Turnitin for checking. In this case, the submission will be resent to Turnitin within 24 hours and there is no need to resubmit your work.
