How to change author url base on your WordPress site

Pasting the following code on your functions.php file will change the default yoursite.com/author/name to yoursite.com/profile/name.
Replace profile on line 4 by any slug you want.

 add_action('init', 'cng_author_base'); 
 function cng_author_base() {     
 global $wp_rewrite;     
 $author_slug = 'profile'; // change slug name     $  wp_rewrite->author_base = $  author_slug; }
