Second domain mapping not working

How long ago did you change your DNS?

a day ago, but im using google dns on my network so it usually accept changes in only couple of hours. i also have to mention that i updated wordpress to 3.6 yesterday.

The dns works fine, with mapping turned off when i type thirddomain.com i get redirected to thirddomain.firstdomain.com but mapping is not working. When i insert domain in list if i uncheck primary it just loads with uld thirddomain.firstdomain.com. if i check primary it show it loads thirddomain.com but after some time it gets error could not load a page.

Check to see if you have a redirect for that domain somewhere.

Hello,
the first, sorry for my english.

I have a wordpress multisite installed in a subdomain
news.mydomain.com

I have content on the following websites:
https://www.mydomain.com
https://www.mydomain.es
https://www.mydomain.fr
https://www.mydomain.de

I have followed all the steps in this topic to get:

https://www.mydomain.com/news/
https://www.mydomain.es/noticias/
https://www.mydomain.fr/informations/
https://www.mydomain.de/info/

I have edit table wp_x_options:
siteurl: https://www.mydomain.com/news/
home: https://www.mydomain.com/news/
…
table wp_blogs:
domain: https://www.mydomain.com
path: /news/

table wp_domain_mapping:
domain: https://www.mydomain.com/news/
…

on my server there are more sites, so I’ve configured in the apache
AliasMach ./info(.*) news.mydomain.com$1

.htaccess file:

RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]

# add a trailing slash to /wp-admin
RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-(content|admin|includes).*) $2 [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(.*\.php)$ $2 [L]
RewriteRule . index.php [L]

wp-config file:

define('WP_DEBUG', false);
define('WP_ALLOW_MULTISITE', true);
define('MULTISITE', true);
define('SUBDOMAIN_INSTALL', false);
define('DOMAIN_CURRENT_SITE', $_SERVER['HTTP_HOST']);
define('PATH_CURRENT_SITE', '/');
define('SITE_ID_CURRENT_SITE', 1);
define('BLOG_ID_CURRENT_SITE', 1);

/* ??Eso es todo, deja de editar! Feliz blogging */

/** WordPress absolute path to the WordPress directory. */
if ( !defined('ABSPATH') )
	define('ABSPATH', dirname(__FILE__) . '/');

/** Sets up WordPress vars and included files. */
define( 'SUNRISE', 'on' );
require_once(ABSPATH . 'wp-settings.php');

displays the wordpress installed on news.mydomain.com correctly,
but NOT the posts, pages, links, etc. and displays the index for each domain.
Example:
https://www.mydomain.com/news OK
https://www.mydomain.com/news/2013/07/31/hola-mundo KO (display https://www.mydomain.com)

CAN SOMEONE HELP??

I wrote wrong in the message this line:
AliasMatch ./info(.*) /var/www/htdocs/news.mydomain.com$1

Why did you do this:

I have edit table wp_x_options:
siteurl: https://www.mydomain.com/news/
home: https://www.mydomain.com/news/

Domain mapping is for mapping domains, It is not for mapping domains and paths

table wp_domain_mapping:
domain: https://www.mydomain.com/news/

I’m not sure what you are trying to accomplish but given the complexity you might want to consider just make each site a separate WP install.

I have just deleted my website and did whole process again and now it’s working.

I want one installation of WP for

https://www.mydomain.com/news/
https://www.mydomain.es/noticias/
https://www.mydomain.fr/informations/
https://www.mydomain.de/info/

where the content of each website is not an wordpress

https://www.mydomain.com/
https://www.mydomain.es/
https://www.mydomain.fr/
https://www.mydomain.de/

@mmovholi – It would be less work in the long run to just have separate WP installs in the folders where you you want WP.
