Hello @aivts
Can I confirm what you mean when you say when I include the multisite lines in the wp-config.php. Are you referring to the following line to Allow Multisite:
define( 'WP_ALLOW_MULTISITE', true );
Or do you mean the lines that your WordPress install presents during the Enabling the Network step?
define( 'MULTISITE', true );
define( 'SUBDOMAIN_INSTALL', false );
define( 'DOMAIN_CURRENT_SITE', 'abc.com' );
define( 'PATH_CURRENT_SITE', '/web/' );
define( 'SITE_ID_CURRENT_SITE', 1 );
define( 'BLOG_ID_CURRENT_SITE', 1 );
If you mean this step, did WordPress also ask you to add some lines to your .htaccess file?
RewriteEngine On
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteBase /web/
RewriteRule ^index\.php$ - [L]
# add a trailing slash to /wp-admin
RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L]
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-(content|admin|includes).*) $2 [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(.*\.php)$ $2 [L]
RewriteRule . index.php [L]
If you are running the server on nginx, the .htaccess file solution might not work (it depends on how the server is configured) and you might need to add those lines to your nginx config manually. Additionally, the nginx config lines are slightly different from the Apache .htaccess ones.
I was able to replicate your environment on my local Apache setup, and enable the multisite on the WordPress install in the /web/ directory, so I’m thinking it might be the nginx configs that are needed.
