Known Issues & Ongoing Problems Status
Empty file submitted to Blackboard Assignment if using Microsoft Edge and opening the file while submitting

Files selected for Assignment submissions and Course Content become replaced with an empty file if a user of Microsoft Windows 10 and the Edge browser has opened and closed the file after selection and before submission.

Resolution/Workaround: Workaround #1:

  • Do not open the source file after selecting it for upload into Blackboard Learn. Users should be advised to open files for inspection before accessing the area to which they wish to upload the file.

Workaround #2:

  • Use different browser such as Chrome or Firefox.
Turnitin Error 124

You may see this error when trying to open feedback on a Turnitin assignment from ‘My Marks and Feedback’.

Error 124: Object ID missing or invalid.

The error occurs when Turnitin and Blackboard have not synchronised correctly.


  • Go directly to the Turnitin Assignment and click on View/Complete (as you did when you submitted your work). See Turnitin: View marks and feedback.
  • Please also notify your Programme Administrator. They can easily resolve the 124 error, but won’t be aware of it unless you tell them.
PDFs opened from Blackboard appear to be blank

Sometimes when you click on a link in Blackboard to a PDF, the file opens in the browser, but only the first page is visible, and the other pages appear to be blank.

Only first page of PDF displays in browser

This is a browser issue, not specifically related to Blackboard.

Workaround: Download the file and then open it

  • Right-click on the link and select Save link as (or ‘Save target as’)Save PDF As dialog box
  • Save the file to a suitable location e.g. your Downloads folder.
  • Open the file. It will probably still open in your internet browser, but should now display correctly.
  • If it still does not display correctly, open Adobe Acrobat and then open the PDF from inside Acrobat.
