I am trying to setup my wordpress installation with multsite support and it's having issues resolving the domain. I followed the steps but I did not change the domain from the initial ip address during setup.

So, I changed the settings in the wp-config.php file as follows:

define('DOMAIN_CURRENT_SITE', '');


define('DOMAIN_CURRENT_SITE', 'www.mydomain.com');

and refreshed the page.

I am now getting a blank page when I try to access the site from mydomain.com but can still accesss the site through the ip address.

There is no actual setting to change the root domain in a wordpress multisite that I can see.

Any ideas why I am getting a blank page when I access my site from the domain name?

My end goal is to setup multi site support with subdomains(e.g. subdomain.domain.com) and http.


Use phpMyAdmin to change the site URL in two locations in the wp_options table. The URL you enter will be the root domain.

  • I am not using phpMyadmin. I am hosting wordpress itself. – SomethingsGottaGive May 26 '18 at 14:20
  • Use whatever database editor you have to edit those two rows in the wp_options table. phpMyAdmin is just a common way to edit databases. – Rick Hellewell May 26 '18 at 18:01
