You have new line before the <!--?php tag or after the ?--> tag in some of theme or plugin files .
Maybe during your customization there is some line breaks (enter ) added before the <!--?php tag or after the ?--> (closing php) tag .
This is creating issues in the javascript that submits the quiz .
YOu will have to check in each of the files you changed for the new line before the <!--?php tag or after the ?--> (closing php) tag in order to resolve the quiz issue .
