ho installato questa contrib (box con i tag cloud, molto utile):
http://addons.oscommerce.com/info/5498
funziona bene, ma deve esserci qualche piccolo errore: come potete vedere qui sotto, quando la "attivo" mi cambia la formattazione del footer..(sfondo rosso invece del bianco e barra che segue la larghezza della pagina invece di rimanere delle dimensioni della tabella..)
qualcuno sa dirmi dov'è l'errore? di php non sono ferrato, ma penso sia 1 cosa facile da risolvere ...
ps. anche cambiando la classe infobox, l'errore rimane
Vi ringrazio in anticipo!
vi allego il codice della contrib:
