Why do I get an error when I log in?

An error occurs when a user is using an incorrectly bookmarked link to log into Canvas.

Please type in the URL for Canvas directly: https://sjsu.instructure.com/ into the browser of your choice.

Canvas users can bookmark it, but only AFTER logging into Canvas, not when on the SSO login page.

I would suggest also the you clear your cache: http://www.wikihow.com/Clear-Your-Browser’s-Cache
