Website blank screen - caused by school content blocking?
I set up three entire year groups on Duolingo recently and just this week, we've encountered blank screens on both iPads and PCs on the school's network. Staff log-ins seem to work OK however. Is it possible that a change in our content filter for students has blocked the website?
It's possible. The easiest solution would be to get the people who manage the content filter to look it over for you. They'll need to set up the exceptions if you want it to work again so you may as well get in touch anyway.
If you are more technical, you can use control+alt+i to bring up a diagnostic window in chrome and reload the page. Differences between the working machines and the student machines will help you see what's going on.
