LMS Known Issues
You can also check if your issue has been resolved.
Java-based applets fail in Chrome 42
The Chrome browser is removing support for tools that use the NPAPI system. In Blackboard this includes drag-and-drop file upload, Virtual Classroom, Chat and some older SCORM objects.
Workaround: Versions of Chrome up to 45 (due in September 2015) can have this feature re-enabled. Users can also use a different browser for these tools. There is currently no timeframe for these issues being fixed in Blackboard.
YouTube Video Mashup tool
Users cannot add a 'YouTube video mashup' through the text editor or via Build Content > YouTube Videos. Regardless of the search entered, only one video called 'Device Support' is returned. Blackboard engineers are aware of this issue and it will be fixed in a future update. Existing YouTube links via the Mashup tool continue to work.
Workaround: Go to the video on the YouTube website and click 'Share' and click on the 'Embed' tab. Copy the embed code. In the LMS: Build Content > Create Item. In Text editor click 'Insert / Edit Embedded Media'. On the 'Source' tab, past the embed code from YouTube. Return to the 'General' tab and click 'Insert' then 'Submit'.
YouTube: Record from Webcam
Users cannot use the 'record from webcam' tool through the text editor. An authentication error is shown instead of the expected interface. Blackboard engineers are aware of this issue and it will be fixed in a future update.
Workaround: Create the video on the YouTube website and click 'Share' and click on the 'Embed' tab. Copy the embed code. In the LMS: Build Content > Create Item. In Text editor click 'Insert / Edit Embedded Media'. On the 'Source' tab, past the embed code from YouTube. Return to the 'General' tab and click 'Insert' then 'Submit'.
New SlideShare mashups cannot be viewed
When a staff member creates a SlideShare presentation the 'Watch presentation' link greys out the screen, rather than showing the presentation.
Workaround: When adding a SlideShare choose 'Embed Presentation' from the View dropdown list instead of 'Thumbnail'.
Test results do not display in some browsers
When a student completes a test and clicks OK, the test results should display. When the test has been set to open in a new page, in some browsers nothing happens when clicking OK. Affected browsers are some versions of Chrome, Safari and Internet Explorer. Firefox works correctly.
Workaround: Return to the Test or Click on My Grades to view the test results, or use a Firefox browser.
Discussion Board: Older images do not display
Discussion Board images added before Dec 8 2014 are not displayed in web browsers. The images are displayed in the BB Mobile Learn App. Newly added images display correctly.
Workaround: View the discussion posts through the BB Mobile Learn App. The images can be downloaded and reinserted into discussion posts.
Discussion Board: YouTube Videos
Thumbnails of YouTube Videos in a discussion board post show a Session Error when the user clicks Watch Video.
Workaround: Click the URL to play the video. When adding You Tube Videos to a discussion board post, choose Embed Video View rather than Thumbnail View.
Blackboard Assignments: New delegated and anonymous grading options
There are known issues affecting particular combinations of the new anonymous and/or delegated grading options that may affect grade centre display. We encourage people to talk with us before using anonymous and delegated grading: http://lms.unimelb.edu.au/support/helpdesk/
Hotspot questions not able to be clicked
When answering a Hotspot question the X does not display where the cursor was clicked.This issue is encountered when using Internet Explorer and Chrome (When the page Zoom is greater or less than 100%)
Workaround: Staff should advise students to use Firefox when attempting tests that contain Hotspot questions or return the browser zoom to 100% before answering Hot Spot questions.
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.
Pasting text in Firefox
Users are unable to copy (ctrl-c) and paste (ctrl-v) content within Firefox in the visual text box editor.
- Paste the text into another program, like a text editor, then copy it again from that program and paste it into the Content Editor
- Use a different browser
- Make changes to the advanced configuration in Firefox:
- Open Firefox
- Type about:config into the address bar
- Search for 'dom.event.clipboardevents.enabled'
- 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.
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.
