我试图在Debian 8.0中安装DAViCal + CalDavZap。并有这个问题：
/etc/apache2/sites-enabled/dav.conf：
# Virtual Host def for Debian packaged DAViCal
<VirtualHost *:80>
DocumentRoot /usr/share/davical/htdocs
DirectoryIndex index.html index.php
ServerName davical.local
Alias /images/ /usr/share/davical/htdocs/images/
Alias /cal /var/www/caldavzap/
<Directory /usr/share/davical/htdocs/>
AllowOverride None
Order allow,deny
Allow from all
</Directory>
php_value include_path /usr/share/awl/inc
php_value magic_quotes_gpc 0
php_value register_globals 0
php_value error_reporting «E_ALL & ~E_NOTICE»
php_value default_charset «utf-8»
</VirtualHost>
和sudo service apache2 restart：
Syntax error on line 18 of /etc/apache2/sites-enabled/dav.conf: Expected </Directory> but saw </VirtualHost>
Action 'start' failed.
你能说我能做什么，我该怎么办？
