I have a Wordpress multisite setup at http://in-autos.com and I have a sub-domain multisite structure and a FQDN http://billgattonsales.com

My trouble:
I can access the Admin area by visiting either the main site, or any sub-domain, but I cannot access the Admin area using the FQDN. So FQDN/wp-admin/ will not work.

What am I missing to get the FQDN/wp-admin/ to work correctly?

The DNS is forwarded, and the site works great from the home page, and sub-pages. Permalinks is working fine.

Server Setup:
I'm running the WP Multisite on a VM behind an Nginx router. Nginx appears to be functioning correctly.

Please tell me what you need. Thank you.

Access Log:

After a few seconds, the screen is blank with no error codes. Error log is empty.

tail -f error.log produces no results.


In my experience WP doesn't like being accessed from anywhere that's not the site url in the wp_config table.

If you want to change the URL to your new(?) one this codex page should help, however it will probably prevent you from accessing by your old(?) url.

  • Thank you Joshua. This is a WP multisite setup, and there's only one wp-config file. Can a second wp-config file be setup just for the sub-domain in a multisite? After searching, I'm not finding anything. Or maybe you're saying that I have to define all sub-domains? If so, how would I do this? – Tom Mar 11 '16 at 21:08
