Install WP multisite in a subfolder and create new sites at the same level as the main install.

Posted on by DomainRooster

We were looking for a fix for around 2 weeks and stumbled across the below. For anyone wanting to move have some other cms installed in the route folder. And then have WordPress installed in a /subfolder, who wants to then create new WordPress subsites at the same level as the main multisite which is located in a subfolder.

Create your multisite.

12/* Multisite */define('WP_ALLOW_MULTISITE', true);

Assuming you know how to do that let’s move on.

Firstly, have your multisite setup in a subdirectory:

  • www.mydomain.com/blog/
  • www.mydomain.com/blog/site1
  • www.mydomain.com/blog/site2

Second, add a directory in the root, this should be the same as the first and second site you just created:

  • www.mydomain.com/site1

In that newly created directory (/site1/), you can add a .htaccess to rewrite all requests to the multisite installation. This code worked for us in the .htaccess file:

RewriteEngine On RewriteBase /

RewriteCond %{REQUEST_FILENAME} !-d

RewriteCond %{REQUEST_FILENAME} !-f

RewriteRule ^(index\.php)$ /site1/$1   

RewriteRule ^(.*)$ /site1g/$1

Now everything should be working, and when you visit www.mydomain.com/blog you should see your multisite subsite. The only problem is that sometimes you cannot log in because of some cookie domain conflicts. To fix this, delete all the domain cookies (use chrome dev tools). Secondly, add these lines to the wp-config.php file:

define('ADMIN_COOKIE_PATH', '/'); 

define('COOKIE_DOMAIN', '');

define('COOKIEPATH', ''); 

define('SITECOOKIEPATH', '');

Hopefully it works for you.
