Known Issues


Submitted Documents appear garbled when viewing/grading in Blackboard Update: July 7, 2014

There is a bug with our current version of Blackboard that causes documents viewed with the Crocodoc grading software to appear garbled, with lines of text appearing stacked on top of one another.  This is a conflict between Internet Explorer 11 and our current version of Blackboard.  

This bug should be fixed with the next update to Blackboard which will be implemented at UK in August 2014.

In the meantime, there are 2 workarounds for this issue:

- Simply use another browser, such as Google Chrome, Mozilla Firefox, or Safari.  These browsers can all be easily found with a web search.

- Change Internet Explorer's Document mode.  To do this, open Internet Explorer and follow these steps:

  1. Push F12 to open the Developer Panel at the bottom of your screen.
  2. Click on the arrow under the icons on the left until you get to the end of the list.  You will see an icon that looks like a computer monitor with a mobile device next to it.
  3. Click on the icon as described above.
  4. In the panel to the right of this icon, the top left option will say "Document mode."
  5. Click on the dropdown box and change it from "8 (Default)" to "Edge."
  6. Push F12 again to close the Developer Panel.
  7. Documents in Crocodoc should now display correctly.

 


Test answers/Feedback not viewable by students after Exam is no longer available Update: June 5, 2014

There is a bug with our current version of Blackboard that will cause students to be unable to view the Feedback for a test (including correct answers, if set that way) after the test is no longer available. This is caused by using the Show Feedback After Availability End Date in conjunction with Test Availability Exceptions. If one or more students are set up to have Test Availability Exceptions, then that test will not display to any students if also set to Show Feedback after the Availability End Date.

This bug should be fixed with the next update to Blackboard which will be implemented at UK in August 2014.
 
In the meantime, the official workaround is as follows:
 
Under Show Feedback (When option) choose "On Specific Date" and then enter the date and specific time that you would like for each Exam and Quiz to become viewable to students in their My Grades section. For the tests where you have an exception that is a later date, simply set this date to be after that exception test date. You may also choose the option "After Due Date.

There is a problem with viewing Lecture videos that has to do with Mixed Content (sometimes referred to as Secure and Non-secure content).  In order to view the lectures, you must configure your browser to display this Mixed Content or else tell it yes if a popup asks you if you want to display it.

Sending email to large number of users (100+) may result in error: HTTP Error 404.15 - Not Found. The request filtering module is configured to deny a request where the query string is too long.   (Verified: Feb. 11, 2014)

If you see this error after sending an email, the email has been sent, and you should receive your copy as usual. The problem is that with the large number of users, the URL is too long to display the "success" message to the sender.

 


Courses that are unavailable to students based on dates appear on the Course List module.    (Verified: Mar. 14, 2014)
