Nginx subdirectory wordpress wp-login redirects to 404 not found

Question

server {
location / {
            try_files $uri $uri/ @extensionless-php;
    }
location /shop {
           try_files $uri $uri/ /shop/index.php?q=$uri&$args /shop/index.php?q=$uri&$args;
    }
location ~ \.php$ {
             if ($request_uri ~ (.*)\.php$)
    {
             return 301 $1;
            }
             try_files $uri =404;
             include /etc/nginx/fastcgi.conf;
             fastcgi_pass unix:/run/php/php7.0-fpm.sock;

        }
location @extensionless-php {
    rewrite ^(.*)$ $1.php last;
}

The above code is used in nginx server file. I have wordpress installed in a subdirectory. When I try to login into my dashboad using username and password through wp-login.php page it redirects to 404 not found. The other pages of the wordpress blog works fine. I cannot access my dashboard only. Please help me to solve the issue. Thanks in advance.

You may want to add a separate (nested) location ~ \.php$ block for WordPress to isolate it from the extension-less PHP rules used for the rest of your site.

For example:

location / { ... }

location ^~ /shop {
    try_files $uri $uri/ /shop/index.php?q=$uri&$args;
    location ~ \.php$ {
        try_files $uri =404;
        include /etc/nginx/fastcgi.conf;
        fastcgi_pass unix:/run/php/php7.0-fpm.sock;
    }
}

location ~ \.php$ { ... }

location @extensionless-php { ... }

The ^~ modifier gives the prefix location higher precedence than the regular expression locations at the same level. See this document for details.
