Blackboard Side Navigation Menu
Posted by Casey Spencer on 09/10/16 8:52 PM

Blackboard side navigation menu missing.

Be advised that the support center is aware of an intermittent and random issue affecting some Blackboard users. After logging on to the Blackboard system and clicking into your Blackboard course shell, you may notice that the left side menu that contains links to Weekly Materials, Assignment Submission, Discussion Board, and other items, may go missing.

If you should experience this, the work around to get the menu to return is to clear your browser's web history/cache. Reports of this condition appear to be more prevalent when using the Google Chrome web browser but some users have reported the condition when using Mozilla Firefox or other browsers. This condition has also been reported by users that were accessing courses on a mobile device such an iPhone. Unfortunately, the work around described above only works on computers, not on mobile devices.

The DU Customer Support Center has reported this issue to Blackboard Corporate Support and their engineers are working on a fix. No estimate on time has been given.

We apologize for the inconvenience. Please contact our office if the suggestion to clear your browsing history does not bring back the missing left side menu (computers only).

Toll free - 800-322-3984. Weekdays until 10PM, Saturday until 4PM, Sunday until 8PM.

Clearing Your Web Browsing History/Cache/Temp Files
Posted by Casey Spencer on 09/24/13 11:02 PM

Many issues are resolved by clearing your web browser's cache (web browsing history). A quick way to do this is a keyboard shortcut that works on IE, Firefox, and Chrome.

Open the browser to any web page and hold CTRL and SHIFT while tapping the DELETE key. (This is NOT CTRL, ALT, DEL).

The dialog box will open to clear the browser. Set it to clear everything and click Clear Now or Delete at the bottom.

Close the browser and re-open it fresh to test what wasn't working for you previously.

For most Mac OS users using Safari, these directions should work for emptying caches:
