title: woocommerce breadcrumb missing shop link
body: <p>I have a WordPress site that uses woocommerce (in internal page), my URL structure for shop page as follow:</p>
  
  <p><strong>mysite/shop/</strong></p>
  
  <p>breadcrumb on woocommerce pages show only home link like :
  You are here: Home</p>
  
  <p>and my product page url: </p>
  
  <p><strong>Mysite/product-category/category_name/</strong></p>
  
  <p>my shop page breadcrumb show as follow:</p>
  
  <pre><code>You are here: Home 
  </code></pre>
  
  <p>also my category page breadcrumb show as follow:</p>
  
  <pre><code>You are here: Home
  </code></pre>
  
  <p>I need to make it show as :</p>
  
  <p>You are here: Home / shopping / category_name</p>
  
  <p>I checked permalinks options but it seems OK .
  I checked breadcrumb.php template file it seems that it consider that shop () page is the home page of my site.</p>
  
  <p>How can I fix this , should i edit breadcrumb.php or there is an error in my settings? 
  Thanks in advance.</p>
