You can use a childtheme override function, for the author meta, the following function will work:
function childtheme_override_postmeta_authorlink() {
//custom code
}
Here’s the original code for reference:
function cleanyetibasic_postmeta_authorlink() {
global $authordata;
$author_prep = '<span class="meta-prep meta-prep-author">' . __('By', 'cleanyetibasic') . ' </span>';
if ( cleanyetibasic_is_custom_post_type() && !current_theme_supports( 'cleanyetibasic_support_post_type_author_link' ) ) {
$author_info = '<span class="vcard"><span class="fn nickname">';
$author_info .= get_the_author_meta( 'display_name' ) ;
$author_info .= '</span></span>';
} else {
$author_info = '<span class="author vcard">';
$author_info .= sprintf('<a class="url fn n" href="%s" title="%s">%s</a>',
get_author_posts_url( $authordata->ID, $authordata->user_nicename ),
/* translators: author name */
sprintf( esc_attr__( 'View all posts by %s', 'cleanyetibasic' ), get_the_author_meta( 'display_name' ) ),
get_the_author_meta( 'display_name' ));
$author_info .= '</span>';
}
$author_credit = $author_prep . $author_info ;
return apply_filters('cleanyetibasic_postmeta_authorlink', $author_credit);
}
