commenti sulla home page del template Nirvana

Buongiorno a tutti. Il mio problema riguarda il template Nirvana sotto 2 diversi aspetti relativi ai commenti.
La prima cosa è permettere i commenti nella home page: quando avevo creato il sito (mesi fa) il cliente mi aveva detto che non li voleva e in qualche modo (che non ricordo) avevo chiuso i commenti.
Ieri dopo mesi mi dice che li rivuole, fosse una normale pagina di WP non avrei problema ma visto che la home page dipende proprio dal tema per la costruzione questa non ha tutte le funzioni di una pagina comune. In sintesi non trovo il modo (dal menù della pagina stessa) di abilitare i commenti.
Tutte le funzioni dei commenti sono abilitate dalla bacheca standard di WP.
La seconda cosa è più particolare, grazie ad un amico che mi aveva creato uno script adatto avevo impostato che i commenti si mostrassero in home page anche se il tema non era predisposto. Questo era il codice
<?php
if ( is_front_page() && is_home() ) {
$withcomments = “1”;
comments_template();
}// Get wp-comments.php template
?>

doveva essere inserito alla riga 165 di includes\theme-frontpage.php.
Ho cambiato il tema (Nirvana appunto) ma alla riga 165 del file suddetto c’è già una parte di uno script.
Ho provato a piazzare il codice a fine file ma mi ha crashato il sito (cosa che ho risolto) ma adesso ho il problema di non sapere dove piazzarlo esattamente.
Questa è òa struttura del file
<?php /*
