比如我新建一个栏目，信息中心，文件夹名为infocenter,然后我新增了一条内容。 在访问的时候出现了404错误，请问这怎么解决呢？ http://localhost/infocenter/40.htm 这个infocenter和40.htm在什么地方呢？

您是不是开启了静态页面，然后没生成静态页？

在那里开启呢？

站点管理里面有静态化

是2.4.2好像没有见到静态化啊

2.4.2的话是缓存，效果和静态话一样

不管访问什么，怎么又出来这个错误啊，无语~~~~~~~~~~~~

看起来好像是jdbc启动都失败了，要不重新安装一下

重新刷新一下就又好了，感觉不稳定啊，还是那个问题，加的内容，依然是404,不管我是否启用了缓存，生成索引，都是404啊，真想撞墙了。
