关于使用phpnuke 建站的问题--在线等！！！！！！

我已经通过phpmyadmin 建立的phpnuke的数据库
通过index.php 访问 出现
Parse error: parse error, unexpected '\"' in /var/www/html/phpnuke/config.php on line 79

Warning: Failed opening 'language/lang-.php' for inclusion (include_path='.:/usr/share/pear') in /var/www/html/phpnuke/mainfile.php on line 48

Warning: Failed opening 'themes//theme.php' for inclusion (include_path='.:/usr/share/pear') in /var/www/html/phpnuke/header.php on line 43

Fatal error: Call to undefined function: themeheader() in /var/www/html/phpnuke/header.php on line 55

是为什么？
