Hello, here is my .htaccess:
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
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]
</IfModule>

# END WordPress

/* Multisite */
define(‘WP_ALLOW_MULTISITE’, true);
define(‘MULTISITE’, true);

hello, yes i did both the wp congif and ht access files modifications
for the database i used Search-Replace-DB-master as recommended on the web. I tried also to update to wordpress 4.5.2 and it tried to access to the /network/ directory but does not seem to find it although it is in place in wp-admin.
