Magento Error – Notice: Undefined index: 0 app/code/core/Mage/Core/Model/Mysql4/Config.php on line 92

I got this error message when migrating my Magento files and database from one server to another.

Notice: Undefined index: 0 in app/code/core/Mage/Core/Model/Mysql4/Config.php on line 92

Solution:

– Open PhpMyAdmin
– Go to your database
– Click SQL
– Run the following SQL Query:

SET FOREIGN_KEY_CHECKS=0;
UPDATE `core_store` SET store_id = 0 WHERE code='admin';
UPDATE `core_store_group` SET group_id = 0 WHERE name='Default';
UPDATE `core_website` SET website_id = 0 WHERE code='admin';
UPDATE `customer_group` SET customer_group_id = 0 WHERE customer_group_code='NOT LOGGED IN';
SET FOREIGN_KEY_CHECKS=1;
