Multisite Network Admin 404 Error

I’ve searched and none of the threads I’ve seen addresses this specific multisite network 404 error.

I’ve installed multisite on a couple of previous sites and they work fine.

This particular site seems to work okay when I go to a site admin: http://website/wordpress/wp-admin/my-sites.php

But when I try to go to the network admin, I get a 404 error.

What appears to be happening is that instead of directing to: http://website/wordpress/wp-admin/network/

I’m taken to: http://website/wp-admin/network/

Here’s the .htaccess:

# BEGIN WordPress
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]

# add a trailing slash to /wp-admin
RewriteRule ^wp-admin$ wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^(wp-(content|admin|includes).*) /subfolder/$1 [L]
RewriteRule ^(.*\.php)$ /subfolder/$1 [L]
RewriteRule . index.php [L]

# END WordPress

And here’s the wp-config:

/* Multisite */
define( 'WP_ALLOW_MULTISITE', true );
define('MULTISITE', true);
define('SUBDOMAIN_INSTALL', true);
define('DOMAIN_CURRENT_SITE', 'daybydaychurchmarketing.com');
define('PATH_CURRENT_SITE', '/');
define('SITE_ID_CURRENT_SITE', 1);
define('BLOG_ID_CURRENT_SITE', 1);
/* That's all, stop editing! Happy blogging. */

Thanks for any help you can provide!
