Quello che hai riportato è il file di classe. Non vengono caricati pacchetti.
Dovresti inviare il preambolo del tuo documento, ovvero ciò che viene prima di \begin{document}. Meglio ancora sarebbe avere un esempio minimo compilabile, ossia un file .tex completo, ma il più breve possibile, che riproduce il problema. Per completezza invia anche la voce bibliografica che dà problemi.Ciao
Ivan
Grazie anche a te della risposta.
Di seguito trovi il mio preambolo. Nel caso questo non servisse a trovare il bandolo della matassa, allora invierò anche un .tex completo.
Ps. il problema è rivolto a tutte le fonti bibliografiche citate. Infatti, nella Bibliografia, vicino ad ogni fonte c’è il collegamento ipertestuale alla pagina nella quale c’è la citazione.
