AYUDA Redux Framework

Estoy probando Redux Framework y cuando modifico el archivo sample-config.php sólo aparece como modificado lo último que he cambiado (3º imagen). No se si falta algo, pero he probado también modificando el código poco a poco cambiando el que hay por defecto por lo que yo quiero y pasa lo mismo. ¿Alguna idea?








Este es el código.

// -> START Basic Fields
Redux::setSection( $opt_name, array(
'title' => __( 'General', 'redux-theme' ),
'id' => 'general',
'desc' => __( 'These are really basic fields!', 'redux-theme' ),

'icon' => 'el el-home'


) );
