Hello @StaciKing ...
Thanks for posting your message. Unfortunately, none of us here in the Canvas Community site have access to your school's Canvas environment or any of your courses to help troubleshoot this. Have you reached out to your instructor to see if you can find out why the information on your course pages isn't visible any more? Your instructor might have a better idea of what is going on.
One thing you can try is to clear your history/cache in your browser. I'm not guaranteeing this will work, but doing this isn't going to harm anything. How do I clear my browser cache and cookies?
You can reach out to your instructor via Canvas by clicking on the "Help" icon on the left-hand global navigation menu and then selected "Ask Your Instructor a Question".
I hope this will be helpful to you. Sing out if you have additional questions...thanks!
