Innanzitutto saluto tutti. Sono nuovo di questo forum così come sono nuovo al linguaggio php.
Ho scaricato il template creative by nature per wordpress da questo sito http://cssmayo.com/freebies/ e non so come modificare gli script per far si che la pagina Portfolio mi mostri solo una certa quantità di item e che alla fine ci sia la possibilità di navigare avanti o indietro per le altre pagine per vedere tutti gli item che ora invece appiano tutti appunto in una sola pagina.

Credo che gli script da modificare siano questi due portfolio.php e functions.php che ora cercherò di farvi vedere. Aiutatemi vi prego che sono settimane che vado avanti con tentativi vani e alla fine ho deciso di rivolgermi a voi che almeno ne sapete qualcosa.

Grazie anticipatamente di cuore a chi vorrà aiutarmi.

questa è portfolio.php

mentre questa è functions.php ridotta nella parte che interessa.
