Metti una miniatura dell'immagine, altrimenti alteri il layout del forum...

[filanico]

Vai nella cartella del plugin.
edita il file 'eventcalendar3.php'
converti i parametri per riferimento in parametri per valore per tutte le funzioni filtro:

/* PRIMA */
function ec3_filter_the_posts(&$posts)

/* DOPO */
function ec3_filter_the_posts($posts)
