域名：zengzhang.in，下面一个 wordpress 程序
nginx 配置如下：

server {
    listen       80;
    server_name  zengzheng.in;
    error_log /var/log/nginx/binge-error.log;

Answer 1

1、请先检查你的index.php有没有问题，也许你关闭了所有错误输出，这是php解析出问题就导致空白页。

2、你的try_files好像和我的不太一样，我的是这样样子，一直正常工作好几年了

try_files $uri $uri/ /index.php?q=$uri&$args;

Answer 2

刚刚遇到了同样的问题，已经解决。
我注意到你的配置文件里面有两个root，第二个location块中有一个$document_root$fastcgi_script_name;此处的$document_root的值可能不是你期望的/var/www/zengzhang.in/，换成这个值试试看。就是把第二个location中的$document_root$fastcgi_script_name换成/var/www/zengzhang.in/$fastcgi_script_name
