Can not login or Magento admin not found after installation

Fresh installation on local
I believe that many people get this problem on setting up their local development environment for Magento project. Everything seems to be fine through Wizard process but you just simply can’t login into Magento admin then. So it is strange? Don’t worry – the most reason for this is that you are using localhost as local domain and this is the problem.

Move / transfer Magento site to new hosting
You might get some errors like this

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

In order to solve this you need to update 4 tables core_website, core_store_group, core_store, customer_group (not all hosting requires these steps – only database not started index from zero is getting this problem)

- Run the following SQL Query:

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';

That’s all. Your error is solved now.

is important to disable foreign key check, otherwise you can update table one by one in this order
core_website, core_store_group, core_store, customer_group

Hope this helps. Thanks.
