Magento: Solution to “Error: 404 Not Found” in Admin Login Page
I transfered my Magento site files from one computer to another. I imported the database. Now, when I try to login to admin (when I go to admin login url), it shows 404 Not Found Error page. The same error is also displayed in the module’s page that are installed in site.
However, the frontend part is working fine. There is no such error in browsing categories and pages in frontend.
If you have enabled System Log in Magento then you can see the log. It is present in var/log/system.log.
It shows the following error:-
Recoverable Error: Argument 1 passed to Mage_Core_Model_Store::setWebsite() must be an instance of Mage_Core_Model_Website, null given, called in YOUR_PATH\app\code\core\Mage\Core\Model\App.php on line 555 and defined in YOUR_PATH\app\code\core\Mage\Core\Model\Store.php on line 285
