我在本地机器上开发了一个小型cakepp网站。当我上传到我的主机服务器时，我意识到我必须使用它们的前缀作为数据库名称和数据库用户。所以，我去创建新的数据库名称和新用户。当我访问该网站时，它是这样的：
Warning (2): mysql_connect() [function.mysql-connect]: Access denied for user old_name @ localhost (using password: YES) [CORE/cake/libs/model/datasources/dbo/dbo_mysql.php, line 552]
我百分之百肯定，我已经把名称改为“new_name”，它在我的本地机器上运行，但我不知道为什么它仍然加载旧名称。我去了ftp，下载了数据库配置文件，它清楚地表明，数据库用户是“new_name”，我不明白为什么当我去网站时，它会加载旧的数据库配置。我是新手，请帮帮我。
试着从app/tmp目录中清除这些文件，然后简单地检查配置。
有时文件可能需要一段时间才能激活。我使用的一台主机有一个上传文件夹，然后它们自动从那里转移到实时文件夹。可能是这样的吗？
