article pages not displaying on local instance of wordpress site

my first thought is that it is a permalinks issue. if it is, set your permalinks to default and the links should work correctly.

also, be sure to search the database for (and replace) any other instances of the old live site’s URL, particularly in wp_posts table. it’s easy to forget to update guid and post_content [i.e., UPDATE wp_posts SET guid = REPLACE (guid, ‘http://www.livesiteurl.com’, ‘http://www.newsiteurl.com’)]
