Nginx WP Multisite – "Warning: An existing WordPress network was detected"

So after applying these changes and restarting Nginx, I reload again the site, but the network setup page gives me a “Warning: An existing WordPress network was detected”.

Why are you accessing network-setup page again? If your network is working fine, you won’t need to goto “network-setup” page again.

You can also try a Nginx config from my https://rtcamp.com/wordpress-nginx/tutorial

I’ve tried your suggestion and used the file from https://rtcamp.com/tutorials/nginx-wordpress-multisite-subdomains-domain-mapping/

This is the /etc/nginx/sites-available/mysite.com config file:

map $http_host $blogid {
default -999;

#Must Read - https://rtcamp.com/tutorials/nginx-maps-wordpress-multisite-static-files-handling/
#foo.example.com 3;
#bar.example.com 4;
}
server {
#@DM - uncomment following line for domain mapping or you will need to add every mapped-domain to server_name$
listen 80;
server_name mysite.com *.mysite.com ;
#@DM - uncomment following line for domain mapping
#server_name_in_redirect off;

access_log /home/myuser/domains/mysite.com/logs/mysite.access.log;
error_log /home/myuser/domains/mysite.com/logs/mysite.error.log debug;

root /home/myuser/domains/mysite.com/public_html;
index index.php;

location / {
try_files $uri $uri/ /index.php?$args ;
}

location ~ \.php$ {
try_files $uri /index.php;
include fastcgi_params;
fastcgi_pass unix:/var/run/php5-fpm-myuser.sock;
#fastcgi_pass unix:/var/run/php5-fpm.sock;
#@DM - uncomment following line for wordpress-plugins that uses value of _SERVER["SERVER_NAME"] e.g.
#fastcgi_param SERVER_NAME $http_host;
}

#WPMU Files
location ~ ^/files/(.*)$ {
try_files /wp-content/blogs.dir/$blogid/$uri /wp-includes/ms-files.php?file=$1 ;
access_log off; log_not_found off; expires max;
}

#WPMU x-sendfile to avoid php readfile()
location ^~ /blogs.dir {
internal;
alias /home/myuser/domains/mysite.com/public_html/wp-content/blogs.dir;
access_log off; log_not_found off; expires max;
}

location ~* ^.+\.(ogg|ogv|svg|svgz|eot|otf|woff|mp4|ttf|rss|atom|jpg|jpeg|gif|png|ico|zip|tgz|gz|rar|bz2|doc|$
access_log off; log_not_found off; expires max;
}

location = /favicon.php { access_log off; log_not_found off; }
location = /robots.txt { access_log off; log_not_found off; }
location ~ /\. { deny all; access_log off; log_not_found off; }
}

No luck though. nd I don’t access the network-setup: when I logout and login again the system goes straight to that page. I haven’t got the normal WP multisite menu to manage sites, it keeps showing me the network setup, and just that. But always with the message “Warning: An existing WordPress network was detected” ??

I’ve finally solved the issue. And it was a really stupid change. When asked to add the typical lines:

define(‘WP_ALLOW_MULTISITE’, true);
define(‘MULTISITE’, true);
define(‘SUBDOMAIN_INSTALL’, true);
$base = ‘/’;
define(‘DOMAIN_CURRENT_SITE’, ‘example.com’);
define(‘PATH_CURRENT_SITE’, ‘/’);
define(‘SITE_ID_CURRENT_SITE’, 1);
define(‘BLOG_ID_CURRENT_SITE’, 1);

I was doing it BELOW the “/* That’s all, stop editing! Happy blogging. */”.

And all I had to do is to insert those lines ABOVE (over) that line. It works now, and it was not a Nginx issue, just a tiny change on the wp-config.php file.

Uauh.

Sorry, forgot to mark this as solved.

Glad to know your issue got fixed. ??
