403 Forbidden apache mac os

Question

帮助设置虚拟主机。在/etc/apache2/httpd.conf文件中，我在此处取消注释了这一行：

# Virtual hosts
Include /private/etc/apache2/extra/httpd-vhosts.conf

接下来，该文件被打开，最后订购了一个新的虚拟主机：

<VirtualHost *:80>
    ServerName localhost
    DocumentRoot "/Library/WebServer/Documents/"
</VirtualHost>

<VirtualHost *:80>
ServerAdmin webmaster@localhost
    DocumentRoot "/Users/igor/sites/advanced"
    ServerName advanced
    ErrorLog "/private/var/log/apache2/lab.domain-error_log"
    CustomLog "/private/var/log/apache2/lab.domain-access_log" common

<Directory "/Users/igor/sites/advanced/">
Options Indexes MultiViews
        AllowOverride All
        Allow from all
        Require all granted
</Directory>
</VirtualHost>

然后添加到主机127.0.0.1高级。重启Apache，但浏览器显示403错误！它可能是什么？
