 * This recently started occurring. I have it on both Safari and Firefox. I believe
   this is in the wpProQuiz_front.js
 * Any help would be great. While I have gotten this far, I am not a coder by any
   means.
 *  I have Enable SCRIPT_DEBUG, which didn’t fix it and then I went onto both Safari
   and firefox and did a diagnosis. They both came back with:
 * TypeError: null is not an object (evaluating ‘json.lock’) wpProQuiz_front.js:
   1953
 * Below are the lines before 1953 and after:
 *  (1948) plugin.methode.ajax({
    action: ‘wp_pro_quiz_check_lock’, quizId: config.
   quizId }, function(json) {
 *  (1953) if(json.lock != undefined) {
    quizStatus.isLocked = json.lock.is;
 *  if(json.lock.pre) {
    $e.find(‘input[name=”restartQuiz”]’).hide(); (1958) }
