我的一个网站出现了一些意想不到的问题，我原以为我的ajax可以正常工作，但后来我注意到它只在firefox中工作。
在chrome控制台中调试时，我看到：

问题在于：

jquery-3.5.1.js:10099 POST https://www.quiz-griz.com/30-how-well-do-you-know-the-vampire-diaries-characters/ajax-answer.php 404 (Not Found)

它试图在重写.htaccess url后加载我的ajax文件，位置就在这里 /ajax/ajax-answer.php 在我的服务器和javascript代码中。
这是引用文件位置的我的代码：

function AnswerQuestion(el) {
  const $el = $(el);
  //alert($el.data('question-id'));
  if ($el.hasClass('disabled'))
    return;
  $el.addClass('disabled');
  const url = '/ajax/ajax-answer.php';
  let pars = {
    answer: $('input[name=questions]:checked', '#question-form').val(),
    takenQuizId: $el.data('taken-quiz-id'),
    quizId: $el.data('quiz-id'),
    questionId: $el.data('question-id'),
  };
  AjaxRequest(url, pars, function(response) {
    // success goes here
    $el.removeClass('disabled');
    console.info("SUCCESS->", response);
    location.reload();
  },
  function (response) {
    // fail goes here
    $el.removeClass('disabled');
    console.info("FAIL->", response);
  });
}

$(document).ready(function() {
  $("#question-form input").on("change", function(){
    $(".btn").removeClass('disabled');
  });
});

这在firefox中运行良好，但在chrome和InternetExplorer中它不想工作。
我想不出要尝试什么，有什么我可以调整来解决这个问题吗？
