problema link bibligrafia

salve a tutti. una mia amica ha un problema con latex e scrivo io per lei, avendo l’account.

praticamente nello scrivere la bibliografia, ha errori di compilazione per quanto rigurda i link da inserire in ciascun punto.
riporto un codice minimo compilabile:

`
\documentclass[11pt,a4paper,oneside]{book}

\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[italian]{babel}
\usepackage{url}
\usepackage[usenames,dvipsnames]{xcolor}
\usepackage[colorlinks=true,urlcolor=blue,citecolor=ForestGreen,linkcolor=blue]{hyperref}
\usepackage{layaureo}
\usepackage{array}
\usepackage{tabularx}
\usepackage{graphicx}
\usepackage{wrapfig}
\usepackage{multirow}
\usepackage{subfigure}
\usepackage{amsmath,amssymb}

Ho provato anche a togliere i $ e \url{}, ma niente, sempre errore…
compila solo se tolgo questo elenco di bibliografia.
