Hi,

Thank you for purchased our theme and your great words.

By default, it will redirect to author page if you click on the author name.

But, if you want to change it to "About Us" page, please add more this code at the end of functions.php of your child theme:

add_filter( 'author_link', 'penci_modify_author_link', 10, 1 );           
function penci_modify_author_link( $link ) {          
    $link = 'http://example.com/';
return $link;                     
}

Best Regards,

PenciDesign
