Magento Admin 404

Question

We recently migrated our Multi-domain magento setup from a shared host to a dedicated server.

All is working fine fronted, but when I try to go to the admin section

Answer 1

Does the dedicated server have mod_rewerite enabled? Does the apache configuration allow .htaccess files to make changes to configuration directives via AllowOverride? Both of those are common ways that the Magento config gets pooched up.

Answer 2

Check in this way

> http://www.yourstore.com/index.php/admin/

or

>  http://www.yourstore.com/admin/

Answer 3

After migration from www.domain1.com/magento/ to www.domain2.com/magento/ I was getting 500 Internal Server Error. So I just renamed my .htaccess to htaccess.txt. And my frontend started working fine, But at Backend http://www.yourstore.com/admin/ I was getting Same 500 Internal Server error.

After trying many option suggested online nothing worked for me and after that I tried to access admin via following URL and voilà worked perfect, Hope this help others.

Try to access as this > http://www.yourstore.com/index.php/admin/

Answer 4

This is an old thread but I've also had an issue with ownership what was returning a 404 in admin. I'd been doing some work on securing the server and some files were owned as root, not apache. So a chown -R apache:apache . fixed it right up.

-- You need to go your server directly and do this via SSH/ FTP

You have to delete the following file

app/etc/use_cache.ser

If you get an error after that like

Notice: Undefined index: 0 in /srv/www/vhosts/javra.com/htdocs/munchad2/app/code/core/Mage/Core/Model/Mysql4/Config.php on line 92

Then go to your Database Management.

• 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;

Some thing strange happens with the cache when you move the databases from one server to another so it seems like you need to clear it out.
