I got a problem trying to access the landing page typing domain.com instead www.domain.com If I type domain.com/rus the WP goes to domain.com/rus/wp-admin/install.php
but if I type www.domain.com/rus the landing page is loaded correctly if I type any address of known pages or post without the www the pages and post are loaded correctly, the main problem is the home page.
I have other site with same information http://www.domain.es/eng and this is working perfectly, now I´m planing to have a site in rusian :) but I got this error and I don´t want to transfer 400M of images again.
There aren´t blank spaces in wp-config.php ( i´ve solved this issues since 4 years ago) the .htaccess shows this code same as site eng (obviusly its own /eng and /rus folder) RewriteBase /rus/
RewriteRule . /rus/index.php [L]
