modificare php..help!

[Martina Stella]

Salve a tutti ho trovato un plugin che permette di inserire gli articoli nelle diverse pagine del sito. Il problema è che riporta soltanto i titoli degli articoli. I vorrei che apparisse un riassunto, magari sfruttando anche il plugin Evermore che già ho. comunque questo plugin è Post Page Associator.

Credo davvero che basti poco però io non so come modificare il php e quindi lascio a voi....
