How to solve Magento admin 404 error

The important thing you need to know is that although 404 errors do not impact your Magento 2 website’s rankings in Google Search Results, they do consume the already limited crawl budget, which finally brings you unwanted losses. Therefore, it’s crucial to fix 404 pages not found errors in your online store as soon as you identify them. Since there are multiple possible reasons for this, there are some possible solutions as well. You can do it one by one until the problem is handled.

1. Recheck your admin URL in env.php

  • Firstly, you move to app/etc/ and open the env.php file.
  • In this file, search for the admin URL code, which should be like below:
return array (
'backend' =>
array (
'frontName' => 'admin_q76xvk',
),
  • If the URL code is different, ensure to type the above admin URL code correctly.

2. Flush Magento cache

Also, you can flush Magento cache by following the below command line:

php bin/magento cache:clean
rm -rf var/cache/*
rm -rf var/generation/*

3. Serve files from the /pub directory

This method is specifically for users on Magento version 2.4.2 and above. The cause for this is that you may run into a 404 not found error after a fresh install of Magento 2.4.2 is due to a change starting from Magento 2.4.2, which asks you to set up the webroot to /pub/ for better security.

To solve this problem, we suggest you follow the official guide by Magento. The whole process includes some steps such as: editing your server configuration, updating the base URL, updating the env.php file, and switching mode.

4. Add/replace .htaccess file in the root folder

Add/replace the default .htaccess file in the root folder with the official .htaccess file from the Magento codebase.

RewriteEngine on
RewriteCond %{REQUEST_URI} !^/pub/
RewriteCond %{REQUEST_URI} !^/setup/
RewriteCond %{REQUEST_URI} !^/update/
RewriteCond %{REQUEST_URI} !^/dev/
RewriteRule .* /pub/$0 [L]
DirectoryIndex index.php

5. Delete var/cache folder

At last, if the above 4 methods don’t fix all 404 errors in your Magento 2 store, then it’s high time to delete the var/cache folder.

Once you’ve deleted the folder, move to database SELECT * FROM core_config_data WHERE path = ‘web/seo/use_rewrites’ and change it to 0.

After that, enter the following URL in your browser:

magento_base_url/index.php/your_admin_url
