I'm working within a child theme so I don't want to edit the file that is registering a Portfolio CPT to my site. I used a plugin to change the name from Portfolio to Stories, but the plugin doesn't give an option for the slug.

I tried using the following function:

function change_slug_of_post_type_portfolio() {
    register_post_type('portfolio', array('rewrite' => array ('slug' => 'stories',)));
}
add_action('init', 'change_slug_of_post_type_portfolio', 20);

But it removes Portfolio entirely from the WordPress admin sidebar.

The register_post_type_args filter can be used to modify post type arguments:

add_filter( 'register_post_type_args', 'wpse247328_register_post_type_args', 10, 2 );
function wpse247328_register_post_type_args( $args, $post_type ) {

    if ( 'portfolio' === $post_type ) {
        $args['rewrite']['slug'] = 'stories';
    }

    return $args;
}

@dave-romsey answer didn't work for me, PHP kept telling me Warning: Cannot use a scalar value as an array in /path/to/functions.php So I went the array_merge way.

Complete function you need to add to your child's theme functions.php file:

function update_portfolios_slug( $args, $post_type ) {

    if ( 'portfolios' === $post_type ) {

        //$args['rewrite']['slug'] = 'presidentes';

        $my_args = array(
            'rewrite' => array( 'slug' => 'presidentes', 'with_front' => false )
        );

        return array_merge( $args, $my_args );
    }

    return $args;
}

add_filter( 'register_post_type_args', 'update_portfolios_slug', 10, 2 );

After uploading your code don't forget to "refresh" your Permalinks by going to Settings > Permalinks and hitting Save changes.

Cheers.
