Move old apache project

[Replace]

HI again, guys. I have another trouble with own old projects basec on large
htaccess rewriet rules.
That's my configuration http://pastebin.com/7JCmiaSm in server block for one
site, and everything work fine except when open url without "index.php"
there. Nginx return me "Access denied", and i can't understand why.
