Well in quiz the answer to question is recorded as comment to the question from the user submitting the quiz .
so there are many insert queries run in the database .
previously all the answers are submitted in on go , means 100 insert queries to database is executed in one go which eventually crashes website and database itself ,
therefore we changed the logic of it and we created a chained ajax call to submit each answer one by one .
and we cannot change the logic based on customer now .
There are other ways to make it work
please contact your webhost and simply whitelist this particular action to the file admin-ajax.php
the other way would be to break your quiz to smaller parts which will have lesser questions
100/4 = 25 question
