KBS_ARTICLE_SLUG
The KBS_ARTICLE_SLUG constant enables you to change the post type slug of the article post type.
By default the slug is article which means that URLs will look like http://yoursite.com/articles/ for the article archive and http://yoursite.com/articles/article-name for individual articles but by defining this constant within your theme’s functions.php file, or any custom plugin file, you can update the slug to be anything you want.
