PHP解析错误语法错误，文件意外结束

当我在 LEMP 设置 nginx 1.10/PHP 7 时，我一直收到此错误，我认为这是因为 PHP 7，现在我使用 nginx 1.4.6/PHP 5.5.9 设置了一个新服务器

2016/06/19 15:45:18 [error] 4094#0: *1 FastCGI sent in stderr: "PHP message: PHP Parse error:  syntax error, unexpected end of file in /var/www/www.example.com/public/wp-content/themes/techs/functions.php on line 141" while reading response header from upstream, client: 10.0.0.11, server: www.example.com, request: "GET / HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "example.com"

现在导致此错误的文件在这里，我注意到该行是空的最后一行，我试图删除该行但不会被删除。谁能指出导致此错误的原因？

纳米/var/www/www.example.com/public/wp-content/themes/techs/functions.php

第 141 行是结束标签之后/下方的空行；每次删除该行的尝试都失败了
