nginx - php: No input file specified.

hey guys i added the following lines to my config

location /mcv {
rewrite ^(.*)$ /public/index.php?uri=$1 last; break;
}

now i keep getting the error 'No input file specified.' when in directory /mcv whcih i believe has something to do with php from what i read...after trying suggestions on articles i found i'm now stuck.

funny thing is i don't get that error anywhere else and php script work in all other dirs other than /mcv

here is my config if someone can please help to me why php isn't working
