tried to follow this post: http://wordpress.org/support/topic/exclude-posts-from-wp_query
but no luck, doesn't seem to exclude the categories in that category. any ideas?
here is the code:
<?php
/*start lukasz edit to exclude cats */
$args=array(
'category__not_in' => array(125),
);
$query = null;
/* end lukasz edits */
$query = new WP_Query($args); /* lukasz: added $args in query, take out of errors*/
$query->query('posts_per_page='. $number );
while ($query->have_posts()) : $query->the_post();
?>
