I have setup multisite wp for multi-language. & created a child-theme of twentytwelve to use across all sites.
My structure is subdirectory multisite domain.com
I dont want to use any multi-language or auto-translate plugins because I've natively translated all sites already.
I just want to add language meta tag for each sub-site. For example for Hindi website domain.com/hi should show lang as hindi
I use common child theme (which follow uniform design across the site) & I dont wish to create separate themes for each sub-site.
How to add language attribute to these subsites?
I dont see "Site language" option in the Settings->General subpanel. (as stated in http://codex.wordpress.org/Installing_WordPress_in_Your_Language#Multi-Site_Installations )
