Image Carousel没有回应

Question

我遇到的问题是我的图片轮播不再有效。它在网站更新之前工作，但我找不到错误。我希望一双新鲜的眼睛可以帮我弄清楚问题。

<div id="carousel1" class="carousel slide" data-ride="carousel">
  <ol class="carousel-indicators">
    <li data-target="#carousel1" data-slide-to="0" class="active"></li>
    <li data-target="#carousel1" data-slide-to="1"></li>
    <li data-target="#carousel1" data-slide-to="2"></li>
    <li data-target="#carousel1" data-slide-to="3"></li>
    <li data-target="#carousel1" data-slide-to="4"></li>
  </ol>
  <div class="carousel-inner">
    <div class="item active"> <img src="Images/cara2.jpg" width="800" height="533" alt="First slide image" class="center-block">
      <div class="carousel-caption">
        <h3>text</h3>
        <p>text</p>
      </div>
    </div>
    <div class="item"> <img src="Images/cara3.jpg" width="800" height="533" alt="Second slide image" class="center-block">
      <div class="carousel-caption">
        <h3>text</h3>
        <p>text</p>
      </div>
    </div>
    <div class="item"> <img src="Images/cara1.jpg" width="800" height="533" alt="Third slide image" class="center-block" />
      <div class="carousel-caption">
        <h3>text</h3>
        <p>text</p>
      </div>
    </div>
    <div class="item"> <img src="Images/cara5.jpg" width="800" height="533" alt="Third slide image" class="center-block" />
      <div class="carousel-caption">
        <h3 class="cara2">text</h3>
        <p class="cara2">text</p>
      </div>
    </div>
    <div class="item"> <img src="Images/archery (4).jpg" width="800" height="533" alt="Third slide image" class="center-block" />
      <div class="carousel-caption">
        <h3 class="cara3">text</h3>
        <p class="cara3">text</p>
      </div>
    </div>
  </div>

我不知道该放什么，所以这是代码。
