Hi A
You can do it by adding the following set of codes at the bottom of your theme’s functions.php file. Like always I would ask you to do the following change using a child theme, so this change along with any further change would remain preserved.
function se_change_previous_text( $output, $format, $link, $post, $adjacent ) {
$output = str_replace( 'Previous Article', 'Previous Recipe', $output );
return $output;
}
add_filter( 'previous_post_link', 'se_change_previous_text', 10, 5 );
function se_change_next_text( $output, $format, $link, $post, $adjacent ) {
$output = str_replace( 'Next Article', 'Next Recipe', $output );
return $output;
}
add_filter( 'next_post_link', 'se_change_next_text', 10, 5 );
Thanks
