problem loading knowledge checks in lessons 30 and 31


I am having problems doing the knowledge checks of lessons 30 and 31. After answering the first question of each quiz and pressing the "next question" button, the following error appears on the screen: "An unknown error occurred. Please refresh the page and try again". I have tried reloading the page and logging in from another browser and computer, but I still get the same error. I rechecked the previous quizzes and the one from lesson 32, and they seem to work correctly.


  • Hi @iri36 , I was able to reproduce the issue for Chapters 30 and 31. We'll take a loot at it. Thanks for reporting it!
