I have used Khan Academy to track student progress this year (and for multiple years), and everything has been fine until this week (June 26, 2017). When I click on any of my classes, I get a blank top half of a website, and the bottom half is the 'Donate' or 'Volunteer' ad that covers up the entire bottom half of the page. The website isn't still loading, and nothing comes up. I've tried this on Chrome and Firefox, and both do the same thing.
I'm using Khan progress in my student grades this year, and if I can't access this information about student progress, I will be in a pickle!
