Post Order

$args = array(
    'orderby' => 'name', // Can be 'id', 'name', 'date', etc...
    'order' => ASC // Can be ASC or DESC
);
query_posts($args);

If you are already parsing $args to query_posts() then ensure that you add the above options to those $args, as opposed to redeclaring $args and overwriting them.

From your root folder navigate to ‘/wp-content/themes/{whatever theme}/’ and find a file called ‘index.php’. This is where WP gets the posts that it displays.

Do a search and look for ‘query_posts’ – if you do not find it, copy the code above and place it just before The Loop, which will be identifed by one of the following –

if(have_posts) : while(have_posts) : the_post() ....
template_part('loop', 'index');

Make sure you use a proper eidtor (I use Total Edit), not MS Word, as that will mess the file up. and make sure that the code is inside PHP tags (<?php {Your code} ?>).

No probelem, hope it helps.
