title: Why is Magento not displaying Orders in the admin Backend?
body: <p>We're using Magento 1.9.1.0 and it recently stopped displaying Orders in the Backend under <strong>Sales</strong>-><strong>Orders</strong>. I can't figure out why this is:</p>

  <ul>
  <li>The Orders in the Database seem to be okay. Orders can be placed as usual and they appear in the <em>Dashboard</em> under <em>Last 5 Orders</em></li>
  <li>I reuploaded the original backend-templates into <code>app\design\adminhtml\default\default\template\sales\order\</code></li>
  <li>Both <code>var\log\system.log</code> and <code>exception.log</code> show no entries when the page is called</li>
  <li>Other people reported that the grid-view table is only partially loaded until it stops at a faulty data-set and is therefore not displayed, however in my case the page's source contains no more than an empty <code>&lt;div&gt;&lt;/div&gt;</code></li>
  </ul>
  
  <p>Any hints or suggestions greatly appreciated!</p>
  
  <p>Thanks</p>
