I just received an email from a student saying when he tries to access this week's module he gets the "Unauthorized - It appears that you don't have permission to access this page" message. I've checked the module for the things that would normally cause this, like prerequisites, requirements, lock until dates, and unpublished content, and it does not have any of those. I can tell other students have been able to access the module because they have taken a quiz in the module. It's the eighth week of the course and this student hasn't had any problems before. Does anyone know what could be going on to cause this one student to see the unauthorized message for this one module?
