出了什么问题，致命错误：base_url不正确

Question

config.php定义如下：

$base_config['base_url'] = 'http://localhost/sg-cms/';

    $base_config['db_host'] = 'localhost';
    $base_config['db_name'] = 'sg-cms';
    $base_config['db_user'] = 'root';
    $base_config['db_pass'] = '';

    $base_config['theme']   = 'basic';

    $base_config['allow_5_4'] = false;

    $base_config['salt']            = 'dfsfdsfdsfasfafasfsfadfvdfdfsfa';
    $base_config['encryption_key']  = 'bjAdffdsfdfadfaJv';

当转到loclhost时，我看到了以下错误：

  

致命错误：base_url不正确：＆＃39; http://localhost/sg-cms/＆＃39;不匹配＆＃39; http://localhost/SWEBSITES/t_m/website/index.php＆＃39;在第277行的C：\ wamp \ www \ SWEBSITES \ t_m \ website \ includes \ routing.php

这里究竟出了什么问题，因为看起来当我修复其他东西时会被破坏！
