[Solution] Sort results by names

For those who are looking for this, if you want to display the locations by name and not by distance, just add the code below to your function.php :

function my_custom_sm_location_sort_order( $original ) {
    return ' posts.post_name ASC';
}
add_filter( 'sm-location-sort-order', 'my_custom_sm_location_sort_order');
