Multiple-choice questions not accepting correct answers

[borsec-suveran]

Initially mulitple questions were accepting correct answers, but after moving through the course, the software began marking all choices as incorrect. This happens even after logging out and is not specific to Chrome, but happens with Firefox as well. It's like the testing component of the software crashes at some point. This started to happen in the Datatypes and Variables section. After that, the subsections or modules (How Computers Work, What is a Data Type, etc.) no longer record completion (designated by the green dot) and therefore can no longer track student progress.

Can you please link to a specific part in the course to replicate?

This is the best explanation I can give. I really do not know the exact point in the course that the quizzes stopped working. Currently none of the quizzes are working, even the ones that were previously working at the beginning of the course. All answers are marked as incorrect. My only suggestion would be to go through the course as a new user and complete a few modules until you experience the same problem. I'm sorry I can't be more helpful than that. But this is a big issue, because it prevents the student from using the quizzes, which is a core component of the course.
