Occasionally there will be a problem that keeps you from doing what you want to do in OWL. Sometimes the problem has to do with something that you have done, sometimes it is a problem with how one of your assignments has been created by your instructor, and sometimes it is a problem with the OWL system itself. What you should do depends on the type of error that you’ve encountered. For all errors, you’ll see a page without a menu bar. The page itself will describe the error and tell you what to do next.
