在Digital Ocean(Ubuntu,PHP,Slim,Twig,PuTTY,FileZilla,Apache)上托管PHP项目后路由器不起作用

I have been trying to host a website (php project) on Digital Ocean using Ubuntu and apparently it's pretty complicated for the inexperienced. I uploaded all files to var/www/html using FileZilla and the main router doesn't work. Instead of domain/login router the only router that works is domain/index.php/login. I'll show you - http://www.itayperry.com/index.php/login

Why does this happen? The index.php should'nt be there. I would love for some help :)

BTW, the project is built in a Slim Framework (with Twig) and the main file is index.php containing a routers.php requirement indise of it.
