1、請先檢查你的index.php有沒有問題，也許你關閉了所有錯誤輸出，這是php解析出問題就導致空白頁。

2、你的try_files好像和我的不太一樣，我的是這樣樣子，一直正常工作好幾年了

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

剛剛遇到了同樣的問題，已經解決。
我注意到你的設定檔裡面有兩個root，第二個location塊中有一個$document_root$fastcgi_script_name;此處的$document_root的值可能不是你期望的/var/www/zengzhang.in/，換成這個值試試看。就是把第二個location中的$document_root$fastcgi_script_name換成/var/www/zengzhang.in/$fastcgi_script_name
