WordPress – 404 Error for Permalinks with Apache Alias and WordPress

.htaccessapache-2.4mod-aliasWordpress

I have scoured several pages, answers and articles in an attempt to correctly configure Apache Alias and WordPress Permalinks without success. 

/var/www/
| - example.com (Custom Web App)
| - blog.example.com (WordPress)

Using the structure above, I am able to access WordPress without any issues, including permalinks such as https://blog.example.com/sample-post/.

I have added an alias in Apache as shown below:

<VirtualHost *:443>
    ServerName example.com
    DocumentRoot /var/www/example.com/public
    Alias /blog /var/www/blog.example.com

    <Directory /var/www/example.com/public>
            AllowOverride all
            Options -Multiviews
            Require all granted
    </Directory>
</VirtualHost>

After making those changes, restarting apache and updating the wordpress address and site address in the WordPress settings area, I can access the site at the desired URL https://example.com/blog but permalinks return 404 errors.

I find that I must switch to plain URLs to get posts to load. I have made no changes to the .htaccess file, however this is the content: 

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

The objective is to access WP posts at https://example.com/blog/sample-post/

Any help is appreciated.

I solved the same issue by changing the configuration.

When you use Alias /blog then accessing WP posts using permalink example.com/blog/sample-post/ will be redirected to example.com by Apache so you get 404 error.

I was using Reverse Proxy and to ignore redirects my setting was: 

<Location /blog/>
  RewriteEngine off
  ProxyPass !
</Location>

Now for Alias /blog we should change following RewriteRule to apache configuration to allow permalinks wroks: 

<Location /blog/>
  RewriteEngine off
  ProxyPass !
  <IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /blog/
    RewriteRule ^index\.php$ - [L]
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule . /blog/index.php [L]
  </IfModule>
</Location>

It works for me.
