Language .po and .mo totally ignored

Maybe this will help?

Install sage9 language files?

Actually you can put your language files anywhere you want - you just need to tell Wordpress about that folder. e.g. you can put your language files directly in your theme directory under resources/lang and add this action to setup.php: add_action( 'after_setup_theme', function () { load_theme_textdomain( 'sage', get_template_directory() . '/lang' ); } );
