How To Fix Magento Admin 404 Error

/in /by

If you are having a problem with the Magento admin area showing a 404 error then this maybe due to many things.

If you have moved the site to a new server then this is normal as Magento requires you to delete the session temporary files and run a query on the database.

Using an FTP client go the folder location /var/

Now remove the content of the following:-

  • Cache
  • Session
  • Tmp

Confirm you have the database configuration correctly setup which is located at /app/etc/

Here you have config.xml and local.xml

Now open the database using a Database client.

  • Go to your database
  • Select the main table over area
  • 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;

You should get the result:-

[SQL]
UPDATE `customer_group` SET customer_group_id = 0 WHERE customer_group_code=’NOT LOGGED IN’;
Affected rows: 1
Time: 0.036ms

[SQL]
SET FOREIGN_KEY_CHECKS=1;
Affected rows: 0
Time: 0.033ms

Now try going to your admin area.
