A black triangle with an exclamation mark means Turnitin could not generate a Similarity Index for that file. Hover over it to see why.
Late Submissions are not allowed
-
In the Task or Deadline dropbox, select Feedback Studio.
-
In the Assignment Inbox, select Settings > Optional Settings. See Turnitin's guide to additional assignment settings.
-
Tick the box to allow late submissions and select Submit at the bottom of the page.
Back in ManageBac+, select Submit Coursework to Turnitin on the Task or Deadline.
You can see the new Similarity Index in the Feedback Studio Assignment Inbox. In ManageBac+, it shows after you reopen the dropbox from the Calendar or Tasks page.
Assignment Line Item not found
The most common cause is that Turnitin was turned on for the Task or Deadline after its due date. You can turn Turnitin on at any time, but the integration only works if it is on before the due date.
Edit the Task or Deadline, move the due date to the future and turn on Turnitin at the same time.
Select Submit Coursework to Turnitin in the dropbox to resend files already submitted.
Still showing? The integration credentials may be wrong. Select Feedback Studio for a more specific message.
Go to Settings > Integrations > Partners > Turnitin and make sure the credentials match your school's Turnitin account.
Open the dropbox and select Submit Coursework to Turnitin.
Start Date later than the submissions
Another cause is a Start Date in Feedback Studio > Settings that is later than the student submissions. You can check submission times with the i icon in the Files column.
Move the ManageBac+ due date to the future.
In Feedback Studio, set the Start Date before the first submission.
Select Submit Coursework to Turnitin.
Restore the original due date.
Class Expired
The full message is: "Submissions are no longer allowed because this class has expired and has become read-only."
This shows on Year Group Deadlines and on two-year classes that have been transitioned. Turnitin sets every class to one academic year by default, and it counts ManageBac+ year groups as classes.
Ask your school's Turnitin admin to extend the class. See Turnitin's guide to managing a class.
Select Submit Coursework to Turnitin in the dropbox in ManageBac+.
Spinning wheel icon
The assignment data usually did not reach Turnitin. Select Submit Coursework to Turnitin in the panel on the right of the Task to resend it.
If submissions stay stuck, contact Turnitin support at tiisupport@turnitin.com.
Very high or 100% similarity from one submission
This usually happens on Tasks or Deadlines with a draft and a final version. Turnitin compares the final version with the student's own draft.
When you create the Task or Deadline, go to Feedback Studio > Settings > Optional Settings and choose one of these:
Do not store the draft in the paper repository. The final version is then not compared with the draft.
Do not compare against the student paper repository. This avoids a high index from earlier copies.
To fix one submission: select the Similarity Index to open it in Turnitin and exclude specific sources.
The adjusted index shows in Turnitin only. The ManageBac+ gradebook keeps the original value.
Only Turnitin can remove a paper from its repository. To ask for a removal, the school's Turnitin admin e-mails tiisupport@turnitin.com with the Class ID, the assignment name and the Submission ID.
The due date for the task has passed, and you have already made a submission
Turnitin only accepts a late submission when the student has not already submitted successfully before the due date. A late resubmission of the same paper is rejected.
Turnitin task could not be created. date_due - due date must be after start date
This error, the MD5 error and other errors linked to a passed due date mean the task was not launched in Turnitin before its due date.
Edit the Task and set a due date in the future. A few minutes ahead is enough.
Open Feedback Studio to launch the assignment in Turnitin.
Select Submit Coursework to Turnitin.
oauth_signature, API product inactive or expired, or This integration is not currently enabled
These errors point to the integration credentials.
Go to Settings > Integrations > Partners > Turnitin.
Check that the account ID and shared key match the school's active Turnitin account and the LTI key in the Turnitin admin panel exactly, with no trailing spaces.
If the oauth error continues, contact Turnitin at integrations@turnitin.com.
Object ID missing
The data transfer to Turnitin timed out. Select Submit Coursework to Turnitin in the right panel of the dropbox. If the error is still there after resending, contact ManageBac+ Support.
No Similarity Index column on a deadline
This happens when the deadline was created, or files were submitted, before Turnitin was enabled. Recreate the deadline and upload the submissions again.
The new Similarity Index may show 99 to 100% because it matches the earlier copies. You can exclude these in Turnitin via All Sources.
Things to know
- If Turnitin matches a submission to an earlier paper and you need to know more about the match, contact Turnitin support directly.
