Images not working on subfolder Multisite

Hi there,

I've cloned (with Cloner plugin) the main site '/', to the subfolder '/uk/'.

All images are broken and the media uploader doesn't work.

It uploads images to:

But the image is located in:

In the wp-config.php i have:

/*Define where images are uploaded*/
define('UPLOADS', 'images');

/* Multisite */
define('MULTISITE', true);
define('SUBDOMAIN_INSTALL', false);
define('DOMAIN_CURRENT_SITE', '');
define('PATH_CURRENT_SITE', '/');
define('SITE_ID_CURRENT_SITE', 1);
define('BLOG_ID_CURRENT_SITE', 1);

In the subsite's configuration I have:

Upload url path:

Upload path: /images/sites/#

And my .htaccess looks like:

Options +FollowSymlinks

# 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

I don't know where's the problem, but I need to fix it as soon as possible...

I've gone into a live support session and they've told to post this here.

Thank you so much,
