We just upgraded our site from Magento 1.9.1.1 to Magento 1.9.3.3.
Unfortunately, our site is broken, so I have investigated the issue. The error notification are as follow.
Fatal error: Uncaught Error: Call to undefined method
Mage_ConfigurableSwatches_Helper_Mediafallback::attachProductChildrenAttributeMapping() in /var/www/html/source/app/code/core/Mage/ConfigurableSwatches/Model/Observer.php:59 Stack trace: #0 /var/www/html/source/app/code/core/Mage/Core/Model/App.php(1358): Mage_ConfigurableSwatches_Model_Observer-productListCollectionLoadAfter(Object(Varien_Event_Observer)) #1 /var/www/html/source/app/code/core/Mage/Core/Model/App.php(1337): Mage_Core_Model_App-_callObserverMethod(Object(Mage_ConfigurableSwatches_Model_Observer), 'productListColl...', Object(Varien_Event_Observer)) #2 /var/www/html/source/app/Mage.php(448): Mage_Core_Model_App-dispatchEvent('catalog_block_p...', Array) #3 /var/www/html/source/app/code/core/Mage/Catalog/Block/Product/List.php(160): Mage::dispatchEvent('catalog_block_p...', Array) #4 /var/www/html/source/app/code/core/Mage/Core/Block/Abstract.php(922): Mage_Catalog_Block_Product_Li in /var/www/html/source/app/code/core/Mage/ConfigurableSwatches/Model/Observer.php on line 59
That code block is as follow.
public function productListCollectionLoadAfter(Varien_Event_Observer $observer)
{
if (!Mage::helper('configurableswatches')->isEnabled()) { // check if functionality disabled
return; // exit without loading swatch functionality
}
/* @var $mediaHelper Mage_ConfigurableSwatches_Helper_Mediafallback */
$mediaHelper = Mage::helper('configurableswatches/mediafallback');
/** @var $priceHelper Mage_ConfigurableSwatches_Helper_List_Price */
$priceHelper = Mage::helper('configurableswatches/list_price');
/* @var $collection Mage_Catalog_Model_Resource_Product_Collection */
$collection = $observer->getCollection();
if ($collection
instanceof Mage_ConfigurableSwatches_Model_Resource_Catalog_Product_Type_Configurable_Product_Collection) {
// avoid recursion
return;
}
$products = $collection->getItems();
$mediaHelper->attachChildrenProducts($products, $collection->getStoreId());
$mediaHelper->attachProductChildrenAttributeMapping($products, $collection->getStoreId());
if ($priceHelper->isEnabled()) {
$priceHelper->attachConfigurableProductChildrenPricesMapping($products, $collection->getStoreId());
}
$mediaHelper->attachGallerySetToCollection($products, $collection->getStoreId());
/* @var $product Mage_Catalog_Model_Product */
foreach ($products as $product) {
$mediaHelper->groupMediaGalleryImages($product);
Mage::helper('configurableswatches/productimg')
->indexProductImages($product, $product->getListSwatchAttrValues());
}
}
The old block (Magento1.9.1.0) is follow.
public function productListCollectionLoadAfter(Varien_Event_Observer $observer)
{
if (!Mage::helper('configurableswatches')->isEnabled()) { // check if functionality disabled
return; // exit without loading swatch functionality
}
/* @var $helper Mage_ConfigurableSwatches_Helper_Mediafallback */
$helper = Mage::helper('configurableswatches/mediafallback');
/* @var $collection Mage_Catalog_Model_Resource_Product_Collection */
$collection = $observer->getCollection();
if ($collection
instanceof Mage_ConfigurableSwatches_Model_Resource_Catalog_Product_Type_Configurable_Product_Collection) {
// avoid recursion
return;
}
$products = $collection->getItems();
$helper->attachChildrenProducts($products, $collection->getStoreId());
$helper->attachConfigurableProductChildrenAttributeMapping($products, $collection->getStoreId());
$helper->attachGallerySetToCollection($products, $collection->getStoreId());
/* @var $product Mage_Catalog_Model_Product */
foreach ($products as $product) {
$helper->groupMediaGalleryImages($product);
Mage::helper('configurableswatches/productimg')
->indexProductImages($product, $product->getListSwatchAttrValues());
}
}
To fix the site broken issue, I disabled the color swatch setting on System/Catalog/Configurable Swatches/General Settings.
Then, our site was retrieved. But, of course, color swatch functions didn't work anymore.
To ensure whether this issue is core bug or not, I installed raw Magento 1.9.3.3 on local server. But, the same issue.
Is there any solution?
To solve this issue, we checked the whole custom modules.
app\code\local\Mage\ConfigurableSwatches\Helper\Mediafallback.php
The old developer created this custom module so that new Magento version's Mediafallback.php didn't work. This is the correct original core php file.

Also, these articles maybe help our solution.
