My students are suddenly getting an Access Denied message when they click on modules for my class. This is not a specific lesson or picture. This is just clicking on the tab for Modules. Everything was fine Friday and Saturday. This just suddenly started. Everything is published. I haven't changed anything since that time. I get the same message if I switch to student view, and I've also attempted to access it through my daughter's Canvas account. She can access all her other classes w/o issue, but my class has the Access Denied message. HELP HELP HELP!!!
