Re: sub domain problem
the site urls are setted in WP.
go to your main site dashbord.
in super admin menu, is the link to all your blogs
Under your main site name click on edit
in the first area, enter http://www.emailaya.com (no ending slash)
in the area named path, enter /
in the area in wp1_options, texarea home, enter http://www.emailaya.com/ (with ending slash)
save your changes
Now go to wp-config.php
i suppose you are under sub-domains.
If yes you must see this somewhere
/** The Database Collate type. Don’t change this if in doubt. */
define(‘DB_COLLATE’, ”);
define(‘VHOST’, ‘yes’);
$base = ‘/’;
define(‘DOMAIN_CURRENT_SITE’, ’emailaya.com’ );
define(‘PATH_CURRENT_SITE’, ‘/’ );
define(‘SITE_ID_CURRENT_SITE’, 1);
define(‘BLOGID_CURRENT_SITE’, ‘1’ );
normally all is ok now !
