error

How can I solve this :

Unsupported operand types in
C:\wamp\www\abc\app\code\core\Mage\ImportExport\Model\Export\Entity\Product.php
on line 875

It occurs when trying to export products via the admin panel system -> import/export menu.

Magento have a patch for this issue as SUPEE-6511.

Ask magento support for the official patch file, however the change provided is simple enough. Around line 875-ish in app/code/core/Mage/ImportExport/Model/Export/Entity/Product.php you should update as follows.

-    $dataRow += $stockItemRows[$productId];
+    if (isset($stockItemRows[$productId])) {
+        $dataRow = array_merge($dataRow, $stockItemRows[$productId]);
+    }

Magento – Call to a member function getBackend() on a non-object

Use the following script to list product attributes with non-existant backend models:

umask(0);
require 'app/Mage.php';    
Mage::setIsDeveloperMode(true);
Mage::app('admin');

$entityType = Mage::getSingleton('eav/config')->getEntityType('catalog_product');
foreach ($entityType->getAttributeCollection() as $attribute) {
    if ($backendClass = $attribute->getBackendModel()) {
        try {
            class_exists(Mage::getConfig()->getModelClassName($backendClass), true);
        } catch (Exception $e) {
            echo "Not found the backend model {$backendClass} for product attribute {$attribute->getAttributeCode()}\n";
        }
    }
}

Product – Error: Unsupported Product Type “type”

While reindexing made the symptom of this issue go away for a time, it doesn't solve the problem. The problem for our Magento install was actually an errant product type in the database.

You can find products with this entity type with the following:

SELECT * FROM `catalog_product_entity` WHERE `type_id` LIKE '%type%';

And you can run this to find all entity types currently being used by products:

SELECT DISTINCT `type_id` FROM `catalog_product_entity`;

All we had to do was reset the errant products to a type_id of simple and it solved the problem.

One thing to note is that this can start happening after disabling or uninstalling a module which added support for custom product types. If you remove the code that supports these product types, you need to change the product types in the database and/or remove the products that use them.
