[Open] Turnitin error: ‘Invalid or missing state’

We are aware that some users are seeing the error message ‘Invalid or missing state’ when trying to access Turnitin. This issue has been reported to Turnitin; the following workarounds should re-enable access.

If using Safari or Firefox, we recommend that users try accessing Turnitin via Chrome or Microsoft Edge in the first instance.

If the error persists, we ask that instructors edit their Turnitin assignments to open in the same tab as the Blackboard page. To do this:

  • Click on the chevron next to the Turnitin assignment and select Edit
  • Scroll to the Web link options section and change ‘Open in New Window’ to ‘No’

  • Click Submit at the bottom of the page.
  • You will see a pop-up asking if you would like to change the Turnitin submission to open in a new window; click Cancel.

  • You will exit the Edit page; click on the assignment to check that Turnitin opens in the same tab.

If you experience any problems, please contact the DEO via digital-education@bristol.ac.uk.
