闲着没事发现Typecho已经在去年就更新到1.1稳定版了，就搞了个来安装玩玩，结果在安装的时候怎么倒腾都出错啊，如图（借用论坛ins的图片）：

错误日志大致如下：

[24-Apr-2018 11:41:40 Asia/Hong_Kong] PHP Warning: Cannot modify header information - headers already sent by (output started at /home/rgbcom/domains/xxx.com/public_html/xxxx/install.php:205) in /home/rgbcom/domains/xxx.com/public_html/xxxx/var/Typecho/Cookie.php on line 102

这个最后发现是PHP版本问题，Typecho需要PHP 5.6及以上的环境才能运行。

去虚拟主机后台把默认的PHP版本native切换成5.6就可以了。

然后 set as current ，然后回去安装就一切顺利了。
