How do I get rid of a popup that says "Unauthorized It appears that you don't have permission to access this page. Please make sure you're authorized to view this content. If you think you should be able to view this page, please use the "Help" link to notify support of the problem," on my Canvas? I am authorized to use my canvas, not sure why this pops up. I log in and I am able to use my canvas but this keeps popping up.
