Quizzes stopped working after update

Hi,

After the latest update all the quizzes stopped working properly. Accessing the settings of each quiz, there is nothing to edit, empty(!) (where are my questions, answers and images??? ), the quiz displays on the site with all the questions and answers, however, always counts as 0 points regardless if you get all the questions right, meaning always assumes you got all the answers wrong, and that’s not all, it doesn’t even gives the green or red color anymore when an answer is chosen, it always stays with a yellow color. Also, Facebook sharing stopped working. Does anyone from the Quiz team gives support at all? I’ve been seeing people with the same issue and no answers for days. Can anyone help at all all of us that are having this problem?

Thank you,
