I have following error after my upgrade :

Fatal error: Call to undefined method Mage_Core_Model_Config::getResourceHelper() in /home/koala/dev/magento/koala/app/Mage.php on line 531 

I ve set up some debug here :

/**
 * Retreive resource helper object
 *
 * @param string $moduleName
 * @return Mage_Core_Model_Resource_Helper_Abstract
 */
public static function getResourceHelper($moduleName)
{
    $registryKey = '_resource_helper/' . $moduleName;
    var_dump($registryKey);
    if (!self::registry($registryKey)) {
        $helperClass = self::getConfig()->getResourceHelper($moduleName);
        self::register($registryKey, $helperClass);
    }

    return self::registry($registryKey);
}

And the resource helper called is :

string(21) "_resource_helper/core"

Does anyone had and fixed this issue?

Thanks

  • I had a deeper look and all the calls to core getResourceHelper are made by magento from core folder, not a single thing is calling this in local so it is not due to custom developments

I fixed this, we had in local an override on app/code/local/Mage/Core/Model/Config.php that was broken

  • In this override function was missing, so basically once added, it works
