Our themes come with Custom Post Types, for example, Portfolios, Galleries, etc.
Each custom post type has a "slug", or to put it simply: a friendly name for URLs and people to read.
As a default rule we name each slug under the English version of the Custom Post Type. So for example, your URL for a Portfolio post would be something like: http://www.yourdomain.com/portfolio/portfolio-name.
If you wish to alter the name of your post type (for example, if you want instead of "portfolio" to say "work") follow the guide below:
1. Open the respective file under theme_functions/post_types/. The php file you are looking for in most cases has the same name as its CPT, so for Artists it would be theme_functions/post_types/artists.php.
2. Find the piece of code:
$args = array( 'labels' => $labels, 'singular_label' => __('Artists Item', 'acoustic'), 'public' => true, 'show_ui' => true, 'capability_type' => 'post', 'hierarchical' => false, 'has_archive' => true, 'rewrite' => array('slug' => 'artists'), 'menu_position' => 5, 'supports' => array('title', 'editor', 'thumbnail') );
Notice this line:
'rewrite' => array('slug' => 'artists'),
Convert it as follows:
'rewrite' => array('slug' => 'musicians'),
Notice that "musicians" should be the word that you wish.
Hit save, upload and then go to Settings -> Permalinks in order for your permalinks to be regenerated.
That's all :)
