You may have issue in "/app/code/core/Mage/Adminhtml/Block/Sitemap/Grid.php". So check the file. Here is a code of Grid.php
class Mage_Adminhtml_Block_Sitemap_Grid extends Mage_Adminhtml_Block_Widget_Grid
{
public function __construct()
{
parent::__construct();
$this->setId('sitemapGrid');
$this->setDefaultSort('sitemap_id');
}
protected function _prepareCollection()
{
$collection = Mage::getModel('sitemap/sitemap')->getCollection();
/* #var $collection Mage_Sitemap_Model_Mysql4_Sitemap_Collection */
$this->setCollection($collection);
return parent::_prepareCollection();
}
protected function _prepareColumns()
{
$this->addColumn('sitemap_id', array(
'header' => Mage::helper('sitemap')->__('ID'),
'width' => '50px',
'index' => 'sitemap_id'
));
$this->addColumn('sitemap_filename', array(
'header' => Mage::helper('sitemap')->__('Filename'),
'index' => 'sitemap_filename'
));
$this->addColumn('sitemap_path', array(
'header' => Mage::helper('sitemap')->__('Path'),
'index' => 'sitemap_path'
));
$this->addColumn('link', array(
'header' => Mage::helper('sitemap')->__('Link for Google'),
'index' => 'concat(sitemap_path, sitemap_filename)',
'renderer' => 'adminhtml/sitemap_grid_renderer_link',
));
$this->addColumn('sitemap_time', array(
'header' => Mage::helper('sitemap')->__('Last Time Generated'),
'width' => '150px',
'index' => 'sitemap_time',
'type' => 'datetime',
));
if (!Mage::app()->isSingleStoreMode()) {
$this->addColumn('store_id', array(
'header' => Mage::helper('sitemap')->__('Store View'),
'index' => 'store_id',
'type' => 'store',
));
}
$this->addColumn('action', array(
'header' => Mage::helper('sitemap')->__('Action'),
'filter' => false,
'sortable' => false,
'width' => '100',
'renderer' => 'adminhtml/sitemap_grid_renderer_action'
));
return parent::_prepareColumns();
}
/**
* Row click url
*
* #return string
*/
public function getRowUrl($row)
{
return $this->getUrl('*/*/edit', array('sitemap_id' => $row->getId()));
}
}
