LMS Known Issues

You can also check if your issue has been resolved.

Turnitin iPad app does not load assignments with > 300 submissions

If using the latest version of the Turnitin iPad app (1.3.0) the wait icon just spins endlessly for assignments with > 300 submissions.

Some earlier versions of the app show an error: "GradeMark Unavailable - Turnitin for iPad cannot be used for this assignment because GradeMark is currently unavailable for this class."

Work around: Use a computer with browser to mark the Turnitin assignment.

Flickr "view photo" function does not work

Users click on view photo to see an expanded version of the photo and get error message: "We are unable to display the mashup content. This happens if the system detects an invalid URL. Remove the mashup item and try again to resolve this".

Workaround: Open the preview in a new tab/window.

Pasting text in Firefox

Users are unable to copy (ctrl-c) and paste (ctrl-v) content within Firefox in the visual text box editor.


  1. Paste the text into another program, like a text editor, then copy it again from that program and paste it into the Content Editor
  2. Use a different browser
  3. Make changes to the advanced configuration in Firefox:
    1. Open Firefox
    2. Type about:config into the address bar
    3. Search for 'dom.event.clipboardevents.enabled'
    4. Double click the search result item to toggle value from 'true' to 'false'

Group Member Import fails with Access Denied error

When staff attempt to import a large (>150 users) group membership .CSV file they receive an Access Denied error. This is an intermittent error, not occurring for all subjects. Blackboard are aware of the issue, which is not scheduled to be resolved until SP17 (estimated 2015).

Workaround: Upload CSV files containing < 150 students.

Subject Menu Web Links

Some Web Links in the Subject Menu may display a blank page instead of the chosen URL.

Workaround: Ensure Edit Mode is ON. Click the downward pointing arrow to the right of the Web Link. Select 'Set Link to Open in a New Window'.

If you encounter any other issues with external links, see External content in the LMS post upgrade.

LTI Tool Provider link descriptions must be plain text

When creating a link from the LMS to an integrated tool using the Tool Provider functionality (eg: linking to PRAZE), the description text is sent as a parameter in the 'handshake' between the two systems. If the description contains HTML tags (due to formatted text), the 'handshake' will fail and the link will not work as expected. The text editor in the LMS adds HTML tags automatically when multiple lines of text are typed, so the description must be a single line of non-formatted text.

Group management - import users

When importing a group using a CSV file in the Bulk Group Management tool, the group code needs to exactly match the ones created in Blackboard. During group creation, some groups include a '_gc_' in their code (e.g., Tutorial_gc_1) which is not immediately obvious to the casual observer. This can result in the import attempt failing to update the group membership/properties.

Workaround: Either

  1. hover the mouse over the existing groups list and note the code that appears in the lower left of the screen, or
  2. export the existing groups as a CSV file to view the full existing group codes.

Assignments need to be made unavailable during marking

If an assignment remains available to students while marking, even if the grade centre column has been hidden, students will be able to see the assignment feedback.

Workaround: Make the assignment unavailable (Edit Assignment or Adaptive Release) until marking is complete and the grades/feedback is to be released to students. Grade Centre column will also have to be unhidden to enable students to see their grade.

Changing names of Groups retains old name for active wikis/blogs/journals/podcast feeds

Once you have created groups and made blogs, wikis or podcast feeds based on those groups, if any group member accessed the group while it had the old name, then the group tool will continue to display the old name to students when they access it. Staff will see the new group name in the active assignment area, but when they open the tool the old name will be displayed.

Workaround: Don't change the group names once students have been allowed to access the tools.
