dedecms 不支持 php 5.4.6

dedecms 使用了php方法session_register, 而在php 5.4.X里已经把这个方法去掉了, 所以为了使用dedecms目前最高版本只能用到5.3.X, 我目前用的dedecms版本是V5.7正式版(2012-06-21).

windows browser not using hosts file – but ping is ok

if you are using proxy to connect the network, the hosts file may not work for browser,
but the ping is ok, ping will return the correct ip address you set in hosts file,i haven’t found a solution to make it working, since if not set the proxy, network will totally not work.

hosts文件为什么对浏览器没用呢,而ping返回来的又是正确的IP呢? 有可能是你正在使用代理上网,
目前我也不知道怎么解决这个问题, 因为不设代理的话,网络就完全不能用了
