Wordpress Multisite Setup - New Site Dashboard Error

Question

I have setup multi site on my website with following configs:

wp-config.php

define('MULTISITE', true);
define('SUBDOMAIN_INSTALL', true);
define('DOMAIN_CURRENT_SITE', 'www.mysite.com');
define('PATH_CURRENT_SITE', '/');
define('SITE_ID_CURRENT_SITE', 1);
define('BLOG_ID_CURRENT_SITE', 1);

.htaccess

# 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]

</IfModule>

I have added a new site http://site1.mysite.com

When I am trying to access its dashboard from Network Dash board after creating the site am getting following error:

I have visited wordpress blog also but unable to find the exact solution.

Can anybody help me to resolve the issue?

Answer 1

The issue was resolved by editing sub-domain in cPanel. Just change the sub-domain Document Root from /public_html/site1 to /public_html and clear the Redirection.
