Magento Call to setStore() on Non-Object – How to Fix

magento-1.7

I have created custom shipping module and gets following error:

Fatal error: Call to a member function setStore() on a non-object in /home/devjoand/public_html/includes/src/Mage_Shipping_Model_Shipping.php on line 421

I removed all files including .xml for this shipping module and it still gives me the same error. It doesn't send me to shipping method and stops execution from savebilling controller with above error. I have cleared cache/session and recompile but nothing works. Any help would be appreciated. Thanks in advance!

NOTE: It works fine in my local machine but not working on production server.

Even if you remove the files there are still the config settings that remain the core_config_data table.
When checking the available shipping methods magento looks for the values from the config on this path carriers/{carrier_code_here}/active. Then for all carrier codes that the value on the path mentioned above is 1 it tries to load the shipping method model.
If you deleted the files it does not exist anymore.
So make sure you delete the values from the core_config_data where path like 'carriers/{carrier_code_here}/%'

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

I believe the issue here is that the toolbar_top.phtml file expects to be instanced with a different block:

{{block type="catalog/product_list" name="home.catalog.product.list" alias="products_homepage" template="catalog/product/list.phtml"}}

Should be:

{{block type="catalog/product_list_toolbar" name="home.catalog.product.list.toolbar.top" alias="products_homepage" template="catalog/product/list.phtml"}}

The reason for this is that Mage_Catalog_Block_Product_List_Toolbar has a method called getCollection, where Mage_Catalog_Block_Product_List does not.

The fluent interface (chained method call) receives null from getCollection, and therefore getSize is being called on a non-object.

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";
        }
    }
}
