Always Smarty_Internal_SmartyTemplateCompiler' not found error after some edits

[teethgrinder]

Hello,
 
I use prestashop with nginx + php-fpm on a local server. After first install everything works but when I try to localize some settings I started to get empty product quick view / details page. and now I get 

Fatal error: Class 'Smarty_Internal_SmartyTemplateCompiler' not found in [/size]/home/ytsejam/public_html/myizmirart/tools/smarty/sysplugins/smarty_internal_template.php on line [/size]671

on both frontend and back office.

 

here is my nginx settings. 

 

server {
  # listen 80 deferred; # for Linux
  # listen 80 accept_filter=httpready; # for FreeBSD
  listen 80;

How can I fix this?
