The course will not load on my computer

If the course does not fully load or you see a blank screen when you open it, you may need to clear your internet browser's cache or history. After you've cleared the cache, be sure to close all of your browser windows. Then, reopen your browser and launch Mango again.

In case the problem persists:

  • Check that Flash is enabled and up to date 
  • Check that Javascript is enabled and up to date
  • Try restarting your computer
  • Try accessing Mango on a different internet browser such as Chrome, Firefox, Internet Explorer, or Safari
