I've tried to follow the guide at http://www.howtoforge.com/running-wordpress-on-nginx-lemp-on-debian-squeeze-ubuntu-11.04 as suggested in the post http://forum.nginx.org/read.php?2,222511,222517#msg-222517 , but it still doesn't work. I've copied and replaced the server settings from the guide, and changed the parts pertaining to my server.

Any permalink setting other than default results in a 404 error page when accessing the permalink. The permalinks all have the form http://wp.dev/sitename/sample-page. There's no structure created for the tags month, year etc. in the url.

Could someone please help me?
