When attempting to view a Similarity Report for a Turnitin assignment in Moodle, students may encounter the following error message:
Error message: Your session has expired. You are not allowed to view this paper - M20: 27
Cause
This error occurs when a student is actively enrolled in the Moodle course, but is no longer enrolled in the corresponding Turnitin class roster. This mismatch typically happens if the student was previously dropped from the class directly via the Turnitin web interface.
Resolution
Select your role below for instructions on how to resolve this error:
To re-sync the student's enrollment between Moodle and Turnitin, follow these steps:
- Log in to Moodle and navigate to the affected course.
- Unenroll the affected student from the Moodle course.
- Re-enroll the student in the Moodle course to trigger a fresh roster sync with Turnitin.
- Ask the student to open the Turnitin assignment again in Moodle to verify access.
Next steps if the issue persists: If re-enrolling the student does not resolve the error, please submit a ticket to Turnitin Technical Support so an agent can manually re-add the user to the Turnitin class roster.
If you are receiving this error message, you cannot fix it on your own.
- Contact your course instructor.
- Provide them with the exact error message (M20: 27) and ask them to refresh your course enrollment to restore your access.
