I have created student classes and sent all students the class code and their user name. I am now checking whether they have done the lessons - but some students names come up in grey and when i try to see what they have done I get a page with the following message. This is happening in every class and with a lot of them in some of the classes! I have over 300 students to track! :
404 - Page not found
Can you please let me know how to resolve this - I have to be able to monitor what the students are completing.
Or is it - they only turn blue once they have done a lesson?
