Occasionally when attempting to open a Turnitin Assignment submission in Feedback Studio, you may receive this error message:

You Session has Expired M14 11 Error

This message is misleading, as it does not indicate a problem with your connection to LEO or Turnitin. This error indicates the submission was not able to be processed by Turnitin for one of several reasons, including:

  • There is content or formatting in the file that Turnitin could not read
  • The high volume of submissions at a particular time resulted in server overload and prevented processing
  • The Turnitin service was experiencing intermittent server issues

In most cases, the file submission will not be recoverable and will need to be deleted by an Editing Lecturer and resubmitted by the student.

How to delete a student Turnitin submission

As most errors will be found after the assignment is closed, and Turnitin assignments cannot be resubmitted past the due date when there is already a submission in place, you will need to manually remove the assignment so that the student can submit again.

Note: you must be an Editing Lecturer in the unit to remove a Turnitin submission.

  1. Navigate to your LEO unit and click the Turnitin Assignment link.
  2. Find the submission you need to remove by searching or filtering by group.
  3. Click the Delete button for that submission (the Trash Can icon):
    Delete Submission button
  4. Confirm the deletion when prompted.
  5. You should now ask the student to resubmit their assignment as they did before.

You may also wish to try downloading a copy of the submission before removing it. This may not always work if the file is corrupted, but it is worth trying if you would like to save a copy of the assignment to mark offline if necessary.

  1. To download the originally submitted file, click the Download button (down arrow icon):
    Download submission button
  2. When prompted, save the file to your computer.

Things to remember when removing submissions

Removing a submission through the Turnitin Assignment link will remove the submission, however the originally submitted paper remains in the Turnitin database. Removing the submission and requesting the student resubmit will not match the work against the previous submission for the same assignment.

Asking a student to resubmit after the due date will change the submission date and appear as red, i.e. a late submission. You can safely ignore this, as there is no automatic penalty applied for late submissions.

If the M14:11 error occurs again after re-submission, this indicates that there is a problem with the file. You may need to ask the student to remove passwords, images (particularly background images), page styles, page or section breaks, special fonts, ensure text and tables are within the margins and other design elements before submitting again. With problematic Word documents, saving these as a PDFs instead may make them accepted more easily by Turnitin.

Submissions you remove are not retrievable. Though they may remain in the Turnitin database, this does not mean they will be able to be accessed by Turnitin if you wish to restore them. Students should keep a copy of their assignments if re-submission is necessary, though it is advisable to try downloading the submission first before removing it.
