Orderby: post_title >Problem

Hi,

I can not order the pages by title. How could I do it? I have changed ‘orderby’ => ‘menu_order’, line to ‘orderby’ => ‘post_title’, but it was unsuccessful.

$args = array(
        'post_status' => 'publish',
        'post_type' => 'page',
        'post_parent' => $p['id'],
        'orderby' => 'menu_order',
        'order' => 'ASC',
        'nopaging' => true,

Could you help me in this, please?

Thank you so much!
