#38 Can't login url messed up index.php/login

[Anonymous]

I'm running php5-fpm, nginx,

when I go to login I get a 404 and the url looks like this index.php/login

error log looks like this.

2014/02/24 00:04:37 [error] 30314#0: *85 open() "/var/www/XXXXXXX.com/web/pos/index.php/login" failed (20: Not a directory), client: x.x.x.x, server: xxxxxxxx.xxx, request: "POST /pos/index.php/login HTTP/1.1", host: "xxxxxxxx.com", referrer: "http://xxxxxxx.xxx/pos/"

I imagine the url should be something like /pos/index.php?login but I can't seem to figure out why it won't work. I have lots of other php scripts working. I checked a bunch of other logs but I'm not seeing anything that pertains to this.
