PHP parse error syntax error, unexpected end of file

I keep getting this error when i was on a LEMP setup nginx 1.10/PHP 7 and i thought it was because of PHP 7 and now i setup a new server with nginx 1.4.6/PHP 5.5.9

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"

Now file that is causing this error is here, and i noticed that line is the empty last line and i tried to remove that line but won't get removed. Can anyone point me to what is causing this error?

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

line 141 is the empty line after/under the closing tag; every attemp to delete that line failed
