Nginx + PHP 7 + CI 3

Hi.

Does anyone have an nginx config file for PHP 7 + CI 3?

If I do:

http://www.foo.dev/index.php/Campaigns

This works fine.

But if I do:

http://www.foo.dev

I get a 404.

I'm upgrading a V2.14 application to the current 3.x and I haven't developed in PHP in 6 months and forgotten all the little issues!

Thanks
