title: Recently viewed products not showing
body: <p>I am trying to get the recently viewed products to show on the product page under up-sells.</p>
  
  <p>As per <a href="https://stackoverflow.com/q/8050661/3204827">this</a> and <a href="https://stackoverflow.com/q/19268891/3204827">this</a> question I added:</p>
  
  <pre><code> &lt;reference name="content"&gt;
      &lt;block type="reports/product_viewed" name="product.recently.viewed" as="product_recently_viewed" template="reports/product_viewed.phtml"/&gt;
   &lt;/reference&gt;
  </code></pre>
  
  <p>to the <code>app/design/frontend/base/default/layout/catalog.xml</code> file and I added:</p>
  
  <pre><code>&lt;?php echo $this-&gt;getChildHtml('product_recently_viewed') ?&gt;
  </code></pre>
  
  <p>just below</p>
  
  <pre><code>&lt;?php echo $this-&gt;getChildHtml('upsell_products') ?&gt;   
  </code></pre>
  
  <p>in the <code>app/design/frontend/base/default/template/catalog/product/view.phtml</code> file, but no recently viewed products will show up. What am I doing wrong that the recently viewed products won't show?</p>
