Nginx + PHP5-FPM keep file 404 not found

Question

Help me out from this please and im really new on Nginx and Apache. I installed web Chevereto on Nginx and Apache. On Apache it working but on Nginx it doesnt work. I tried much answer but it seems another wrong with my config. The main-page is working, i can do upload image and the image is uploaded to image-folder (if manually check). its not going to image preview but to 404 Not Found page.

Answer 1

in my experience, please check php-fpm

try to re-install php5-fpm,

sudo apt-get install php5-fpm

and try to restart your php fpm

service php5-fpm restart
