yes, I have.
define(‘WP_ALLOW_MULTISITE’, true);
News:
I tried again for the 7th time and it works so far so good.
Thanks everybody! I’m going to delete all other sites and re install them.
At one Blog I found the wrong code in .htaccess file so I encourage people to go to Network setup and check that out.

thanks, no problem!

with this line define('WP_ALLOW_MULTISITE', true); or without the reply is the same:

This webpage has a redirect loop
but the addresses are different:
1. with: https://mysite.com/wp/
2. without: https://mysite.com/wp/wp-admin/network/

I didn’t delete:define('WP_ALLOW_MULTISITE', true);
I have on the bottom:

define('WP_DEBUG', false);

define('WP_ALLOW_MULTISITE', true);

define( 'MULTISITE', true );
define( 'SUBDOMAIN_INSTALL', true );
$base = '/';
define( 'DOMAIN_CURRENT_SITE', 'art.musicaroundus.com' );
define( 'PATH_CURRENT_SITE', '/' );
define( 'SITE_ID_CURRENT_SITE', 1 );
define( 'BLOG_ID_CURRENT_SITE', 1 );

/* That's all, stop editing! Happy blogging. */

Xephan, I did a check that my PHP and SQL versions are up to date.
And I tried to do installation two ways: buy myself and by Softaculous that is on my host side.
And I always do everything from the scratch.
Is anybody can help me with my last issue:
I created one extra user “xxxx”.
When I log out and log in back I still have this use name “xxxx”!
I cleaned cash but it still there.
How can I clean this out?
Thanks a lot!

I built another mu site and didn’t add any more users and that site when I click on Network Admin give me:
This webpage has a redirect loop
And there is no SuperAdmin.

I have exactly the same problem!
But I already found one difference in the code
after this:
define( ‘MULTISITE’, true );
creativelasso installed:
define( ‘SUBDOMAIN_INSTALL’, false );
they asked me to install:
define( ‘SUBDOMAIN_INSTALL’, true );
Any way it makes no difference.
I still have a string:
define(‘WP_ALLOW_MULTISITE’, true);
is that right?

And When I go https://www.mysite.com/admin it doesn’t work anymore.

Probably I just found something:
I created one extra user “xxxx”.
When I log out and log in back I still have this use name “xxxx”!
I cleaned cash but it still there.
