Multi-site blog – Super Admin – Sites

Something is wrong setup at my multiblog site:

My main blog is at https://rblog.info and my sub-blogs are at https://rblog.info/xxx/

If I login at my main blog https://rblog.info/wp-admin/ and go to Super Admin – Sites I see all my sub-blog listed
On top is the WordPress logo with the main blog’s title

If I try to change to another sub-blog, e.g., “ron” I will be lead to the URL:
https://rblog.info/wp-admin/ms-sites.php?action=editblog&id=11 but still on top is the WordPress logo with my main blog’s title and below it says Edit Site – https://rblog.info/ron
Going from there to the plugins, I still work on the main blog site!!!!

I have to go to add the sub-blog name before the /wp-admin to go to the site:
https://rblog.info/ron/wp-admin/plugins.php

Here is my .htaccess
# BEGIN WordPress
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ – [L]

# uploaded files
RewriteRule ^([_0-9a-zA-Z-]+/)?files/(.+) wp-includes/ms-files.php?file=$2 [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]
# END WordPress

and that is the last part of my wp-config.php
…
define(‘WP_ALLOW_MULTISITE’, true);
define( ‘MULTISITE’, true );
define( ‘SUBDOMAIN_INSTALL’, false );
$base = ‘/’;
define( ‘DOMAIN_CURRENT_SITE’, ‘rblog.info’ );
define( ‘PATH_CURRENT_SITE’, ‘/’ );
define( ‘SITE_ID_CURRENT_SITE’, 1 );
define( ‘BLOG_ID_CURRENT_SITE’, 1 );
/* That’s all, stop editing! Happy blogging. */

/** Absolute path to the WordPress directory. */
if ( !defined(‘ABSPATH’) )
define(‘ABSPATH’, dirname(__FILE__) . ‘/’);

/** Sets up WordPress vars and included files. */
require_once(ABSPATH . ‘wp-settings.php’);

What do I miss?

bye
