How to redirect your author archive link to your “About” page

This code have to be pasted into your functions.php file. Don't forget to replace about on line 4 by the slug used by your "About" page.

add_filter( 'author_link', 'my_author_link' );

function my_author_link() {
	return home_url( 'about' );
}
