修改模板后，首页空白，无法登录

具体是这样的：

我昨天修改了一下登录前首页和登录后首页的模板，增加了两个google广告。

刚开始没啥问题，也更新缓存了。

今天早上一看。输入网址http://www.dong72.com 首页一片空白，但是输入去掉www的http://dong72.com 就可以看到首页。

但是无法登录。输入用户名和密码后，然后进入输入验证问题的页面，输入后，点击提交，说是登录成功，但是还是会自动退出。

把debug设置为1后。下面是错误输出的调试信息。请高手指教

楼主可以还原一下程序

还原程序了。但总得找到原因啊。
否则每次修改模板都会出问题。

还是不知道哪里出了问题。只要一改模板，然后过大约是个小时后就会出现这样的情况。

你修改完了没有出现问题，并不表示没有问题，那是因为你用的还是原来的，只有清除了缓存才是最新的效果。

从后台清除缓存了。当时也没有出现问题。
