Issue: Unable to open files from Blackboard (Server error, 404 – File or directory not found)
Information: Users of the Microsoft Edge browser receive an error when trying to open Word, PowerPoint and other file attachments from Blackboard. Edge attempts to open MS Office files inside the browser but they fail to open.

Embedded Box of Broadcasts videos 

If you are not already logged in to Box of Broadcasts, embedded videos display a message “Please sign into bob and refresh this page”. Clicking on this takes you to the BoB login page in a new browser tab.
After signing in to BoB, you have to return to Blackboard and Refresh the page in order to watch the embedded video.This appears to be intended behaviour, but it can appear to users that the login is not working. Using a WAYFless link as described in our guide Linking to Box of Broadcasts might provide the best user experience.

Blackboard Annotate: Cropped images with text-wrapping not visible 

In some cases, images inserted into Word documents and submitted to a Blackboard assignment do not display in Blackboard Annotate. This applies if students

  • crop the image
  • and use Tight, Through, or Parallel wrapping modes to wrap the text around the image.

Blackboard Rubrics: Percentage range rubrics do not display selected grade to students

If you mark work using a Blackboard scoring rubric which is set up as a Percentage Range rubric, students will see their overall mark, and will see which cells of the rubric have been highlighted. However they will not see the actual score you have assigned for each cell.

Blackboard Rubrics: Changing a Qualitative Blackboard Assignment rubric resets grade to 0.00

If you’ve used a qualitative rubric with your Blackboard Assignment, once you give the attempt you’re making a grade, making any further changes to the rubric will automatically reset the grade to 0. If you need to edit your rubric after the fact, please make a note of the grade you’ve previously assigned as you will have to re-enter it. If you’re using a scoring rubric, the issue does not exist as the new grade will automatically be assigned by the rubric itself.

Blackboard Tests: Auto-Submit on Tests can cause problems for students

We recommend that you do NOT tick the Auto-Submit box when deploying a Test as there is a known issue where, if students have an unreliable internet connection, this setting could lead to their attempts being submitted prematurely.
Blackboard also recommend turning off the “force completion” option, so that if a student experiences technical issues and is logged out of the test, they can resume and complete the test.For further advice on settings to use with timed tests, see Blackboard Tests: Timer, Autosubmit and Force Completion settings


Known Issues: Blackboard Collaborate Status

Blackboard Collaborate: Browser freezes intermittently when sharing application or screen on Windows

Some users have reported that browsers freeze, or becomes unresponsive, intermittently when sharing an application, or sharing their screen in Collaborate Ultra on Windows. This issue does not affect all users and does not occur during all sessions. The issue has reportedly occurred while using different browser versions on Windows.

  • One workaround is to try using a different supported browser until a fix is released.
  • Another possible workaround for moderators who are appsharing presentations is to upload the file to the whiteboard instead, if possible. This is also a best practice for optimizing bandwidth consumption.
  • Use Firefox to Application Share

Known Issues: Turnitin Status
Turnitin: Syncing of marks between Turnitin and Blackboard Grade Centre
Description: Tii is currently investigating an issue which intermittently impacts some users. When instructors update an assignment’s marks in Feedback Studio, the mark is sometimes not getting passed back to the Blackboard Grade Centre.
Recommendation for Staff: Please double check that the marks in Tii and Grade Centre have been updated and there are no discrepancies.
Turnitin: Turnitin now display submission “Due Date” as UTC equivalent of its UK time to students

Recommendation for students: Students are advised to ensure their computers are configured to correct Time Zone and ensure date and time on their computers is up to date.

Turnitin – Issue accessing Turnitin from Grade Centre


Staff were unable to access Turnitin assignment from the grade centre.

Turnitin have resolved this issue. You can now open Turnitin submissions from the Grade Centre (except where anonymous marking is enabled), as well via Control Panel > Tools > Turnitin Assignments (our recommended route).

Turnitin – Time out error: ‘Your session has expired…’


You may receive the following error message when trying to upload a document to Turnitin

Workaround / Solution: 
To continue using Turnitin, please fully close and re-enter this assignment. Refreshing your browser will not resolve this issue.’
You can resolve this by clearing your browser’s cache and cookies. In most cases, this will resolve the issue.
If you still receive this error after clearing cookies and cache, please try a different browser (e.g., if you are using Safari, try Google Chrome).


Turnitin Assignment: Microsoft files generated using Windows can occasionally fail to process when uploaded to Turnitin

Microsoft files generated using Windows, including .doc, .docx, .xls, .xlsx, .pptx, .ppt, .ppsx, and .pps files, can occasionally fail to process when uploaded to Turnitin. Files created using other operating systems are unaffected.

Resolution/Workaround: Convert your file to a PDF before attempting to upload it to Turnitin. This ensures it is in a format we can process gracefully and without any problems. Find out more here.


Turnitin Assignment view page: Turnitin error code

We are aware of some unusual error code appearing at the top of the Turintin assignment view page, e.g  {if(—-.defineProperty&Object)try{v……..). This code is only visible to users with Admin permissions. Doesn’t affect Turnitin functionality. Please continue using Turinitin.

Affected users: BB users with Admin permissions.

Resolution/Workaround: We will be deploying the fix when its most convenient to do so.



Turnitin: Downloading some/multiple files can result in errors

When trying to download multiple Grading papers (papers with markup and similarity layers visible) from the Turnitin Assignment inbox or Feedback Studio, you may encounter issues with some files not downloading. This happens when a file has a very large number of small similarity report matches, making the file large in size, taking a long time to render and become ready to download.

Image showing the Turnitin assignment inbox with papers selected and the "Download grading paper" option highlighted.

If you download multiple files, you may have some of them missing from the zip file generated.

Turnitin are aware of the issue and are working on resolving this.
