title: Magento: Fatal error: Class not found (Google Shopping)
body: <p>Trying to get <a href="http://www.magentocommerce.com/magento-connect/google-content-api-for-shopping.html" rel="nofollow">Google Shopping extension</a> running on Magento Enterprise Magento ver. 1.10.1.1</p>
  
  <p><strong>Catalog > Google Content > Manage Attributes</strong> throws <em>this error:</em></p>
  
  <pre><code>Fatal error: Class 'Mage_Core_Model_Resource_Db_Collection_Abstract' not found in /var/www/html/app/code/core/Mage/GoogleShopping/Model/Resource/Type/Collection.php on line 35
  </code></pre>
  
  <p><strong>Catalog > Google Content > Manage Attributes > Add Attribute Mapping</strong> throws <em>this error:</em></p>
  
  <pre><code>Fatal error: Class 'Mage_Core_Model_Resource_Db_Abstract' not found in /var/www/html/app/code/core/Mage/GoogleShopping/Model/Resource/Type.php on line 35 
  </code></pre>
  
  <p>I installed the extension by copying the files via FTP, not using the Magento Connect manager if that makes any difference?</p>
  
  <p>I'm not sure where to go from here? Google isn't being very productive on this issue!</p>
