Installing wordpress multisite nginx - wordpress

Question

I have been trying to integrate wordpress multisite on magento using this extension
https://fishpig.co.uk/magento/wordpress-integration/
It works fine for single site, but for multisite when I try to enable multisite it will poping out this error:-
error
I have installed wordpress inside magento, here are the paths:
/var/www/html2/ <---- Magento 2
/var/www/html2/wp/ <---- Wordpress
I suspect the nginx could be the issue, but I'm new to nginx, here is my configuration for nginx (/etc/nginx/sites-available/dbr):-
server {
listen 80;
server_name dbr.test.net www.dbr.test.net;

It sounds like a WordPress misconfiguration (?). Is this how you enabled multisite?
define( 'WP_ALLOW_MULTISITE', true );
Administration > Tools > Network Setup
Add lines to wp-config.php as instructed.
