We have received several reports of the Submit button not working when creating or editing Turnitin assignments. Through testing, we have determined that this error occurs when the post-date is more than two weeks after the due date. We have contacted Turnitin and have asked them to look into this as a matter of urgency.
The error does not appear to affect certain non-Chromium browsers such as Firefox and Safari. If you have access to these, please use them to set up your Turnitin assignments.
If you have any concerns or questions, please contact us at firstname.lastname@example.org
