Yeah, the issue has been resolved.
Thank you!
It was an Apache’s misconfiguration, as I supposed.
I’m not the guy who configure it and I supposed it was ok, but no.
Thanks, ninianepress.
I’m not running a subdomain install, so domain.com/newsite should works.
This is my wp-config file:
define(‘WP_DEBUG’, false);
define(‘MULTISITE’, true);
define(‘SUBDOMAIN_INSTALL’, false);
define(‘DOMAIN_CURRENT_SITE’, ‘in-formando.es’);
define(‘PATH_CURRENT_SITE’, ‘/’);
define(‘SITE_ID_CURRENT_SITE’, 1);
define(‘BLOG_ID_CURRENT_SITE’, 1);
My main domain is http://in-formando.es
And I get the 404 error when I try to access to http://in-formando.es/salesianos
I think that it could be an Apache error, cause I think that everything is ok.
Thanks for your support!
