I am getting Fatal error:

Call to undefined method Mage_Catalog_Model_Resource_Category_Flat::loadAllAttributes() in \app\code\core\Mage\Catalog\Model\Category.php on line 301 error.

When I turn on Flat Catalog and index I get the error. The site has been upgraded from 1.3

This Method exists at least in EE 1.12 not. So I think your Mage_Catalog_Model_Category class is not from actual version.
