Fix 403 error on WordPress multisite network using subdomains


I’ve a WordPress installation that I’ve transformed into a multisite network. I’m using cPanel and I’ve followed all the instructions to configure the WordPress installation. I’ve set up the subdomains mode, so for every new website I need to create a subdomain using cPanel of my shared hosting provider.

The problem is that I get a 403 error every time I try to access to a subdomain website. How I can fix this and is the .htaccess code correct?

NB: every subdomain has it’s own directory on the server when it’s created, so for example, if in the cPanel I set the as a subdomain, the relative directory will be created in the root of the server, with the name of I’ve read that the subdomains must point to the main WordPress installation directory. I’ve also setup the wildcard, but without success.

Here is the .htaccess code.

# BEGIN Custom
<IfModule mod_rewrite.c>
Options All -Indexes
Options FollowSymLinks
RewriteEngine On
RewriteBase /
RewriteCond %{HTTPS} !on
RewriteRule (.*) https://%{HTTP_HOST}/$1 [NC,R=301,L]

<IfModule mod_headers.c>
#Header set Strict-Transport-Security "max-age=31536000; includeSubDomains"
Header set X-Content-Type-Options nosniff
Header set X-XSS-Protection "1; mode=block"
Header edit Set-Cookie ^(.*)$ $1;HttpOnly;Secure
Header unset X-Powered-By
Header unset X-Pingback
Header unset SERVER

<FilesMatch "(^.|wp-config(-sample)*.php)">
Order Deny,Allow
Deny from all

# END Custom

# BEGIN WordPress
<IfModule mod_rewrite.c>
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).*) $1 [L]
RewriteRule ^(.*.php)$ $1 [L]
RewriteRule . index.php [L]

# END WordPress

wp-config.php code

if( strpos($_SERVER['HTTP_X_FORWARDED_PROTO'], 'https') !== false) $_SERVER['HTTPS'] = 'on';

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