Tip #80: Known Issues

Tip: As with most new software, Blackboard 9 has a few bugs. In order to track these and help faculty be aware of potential problem areas, we have created a known issues list.

The complete known issues list can be found at

The following known issues are pervasive issues across campus which many users have experienced.

Blogs, Journals, and Wikis

Some users receive error messages and experience intermittent access when attempting to connect to blogs, journals, and wikis. Blackboard has applied a patch which has resolved the issue. If you continue to receive an error message, this issue can be resolved by clearing your browser cache.

To do so:
Close all browser instances then launch a single instance.
For IE8: Tools >> Internet Options >> Browsing History… >> Delete >> check Temporary Internet files, Cookies, and History >> uncheck Preserve Favorites website data >> Delete

For Firefox 3.5 or greater: Tools >> Clear Recent History >> set Time range to Everything >> check Cookies and Cache >> Clear Now

For IE7: Tools >> Internet Options >> Browsing History… >> Delete >> Delete files… >> Delete cookies… >> Delete history…

Safari: Tools >> Reset Safari >> check Empty the cache and Remove all cookies >> Reset
Exit and then re-launch the browser.

For other browser directions, see:

If, after following these steps, the 404 error continues to occur, send an email to to let us know.

Discussion Board Attachments

Students are unable to view files that instructors have attached, and instructors are unable to view files that students have attached using the Visual Text Box Editor.
  • Instructors should use the "Attach File" icon on the Visual Text Box Editor toolbar.

  • Students should use the "Browse My Computer" button in the Attachments section below the Visual Text Box Editor.


Inserting HTML in areas of the course where HTML is not expected can cause parts of the course to be inaccessible or to not function. We suggest that HTML only be incorporated in text areas that have a related Visual Text Box Editor available.

Announcement, Assessment, Assignment, Discussion Board

If an item is setup with a start date but no end date or with an end date but no start date, the item cannot be modified.

For this reason, it is important to either set both a start date and an end date (even if the end date is dated far in the future) or set neither. Also, do not use both availability dates and adaptive release.
