vBulletin Rewrite Rules on nginx

I'm currently using the following nginx rewrite rules for my CMS, Blog, and Forums, which I've found posted in these forums: (Currently, while we're getting this set up, we're working on linode. davidkarol. com, and plan to move over this Friday)

rewrite ^/threads/([0-9]+)(?:/?$|(?:-[^/]+))(?:/?$|(?:/page([0-9]+)?)) /showthread.php?t=$1&page=$2;
rewrite ^/members/([0-9]+) /member.php?u=$1;
rewrite ^/forums/([0-9]+)(?:/?$|(?:-[^/]+))(?:/?$|(?:/page([0-9]+)?)) /forumdisplay.php?f=$1&page=$2;$
rewrite ^/blogs/([0-9]+)(?:/?$|(?:-[^/]+))(?:/?$|(?:/page([0-9]+)?)) /blog.php?u=$1&page=$2;
rewrite ^/entries/([0-9]+)(?:/?$|(?:-[^/]+))(?:/?$|(?:/page([0-9]+)?)) /entry.php?b=$1&page=$2;
rewrite ^/list/([^/]*/)([0-9]+) /list.php?r=$1$2;
rewrite ^/content/(.*) /content.php?r=$1;

I can't load actual threads, posts, and blogs. After making some changes, I'm able to load the members list, along with the list of threads (each forum.) Here's my config file for the virtual host, and then that for nginx itself (slightly modified):

server {
    listen   80;
    server_name example.com;
    access_log /home/sfn/www/example.net/logs/access.log;
    error_log /home/sfn/www/example.net/logs/error.log;
        root   /home/sfn/www/example.net/public_html/;

    location / {
        index index.php  index.html index.htm;
        rewrite ^/live/threads/([0-9]+)  /showthread.php?t=$1&page=$2;
        rewrite ^/live/members/([0-9]+) /member.php?u=$1;
#       rewrite ^/live/forums/([0-9]+)(?:/?$|(?:-[^/]+))(?:/?$|(?:/page([0-9]+)?)) /forumdisplay.php?$
        rewrite ^/live/forums/([0-9]+) /forumdisplay.php?f=$1;
        rewrite ^/blogs/([0-9]+)(?:/?$|(?:-[^/]+))(?:/?$|(?:/page([0-9]+)?)) /blog.php?u=$1&page=$2;
        rewrite ^/entries/([0-9]+)(?:/?$|(?:-[^/]+))(?:/?$|(?:/page([0-9]+)?)) /entry.php?b=$1&page=$
        rewrite ^/list/([^/]*/)([0-9]+) /list.php?r=$1$2;
        rewrite ^/content/(.*) /content.php?r=$1;
   }

   }

    # Pass PHP scripts on to PHP-FPM
    location ~* \.php$ {
        try_files       $uri /index.php;
        fastcgi_index   index.php;
        fastcgi_pass    127.0.0.1:9000;
        include         fastcgi_params;
        fastcgi_param   SCRIPT_FILENAME    $document_root$fastcgi_script_name;
        fastcgi_param   SCRIPT_NAME        $fastcgi_script_name;
    }
}

        map $scheme $server_https {
                default off;
                https on;
        }

        ##

        include /etc/nginx/conf.d/*.conf;
        include /etc/nginx/sites-enabled/*;
}

In addition, the rules being used on the old Apache server in each directory are below:

Here is the rewriting section I was using on Apache from first the root folder, than the forum and blog stub directories:

Root:

RewriteCond %{REQUEST_FILENAME} -s [OR]RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d

RewriteRule ^.*$ - [NC,L]

# Forum
RewriteRule ^threads/.* showthread.php [QSA]
RewriteRule ^forums/.* forumdisplay.php [QSA]
RewriteRule ^members/.* member.php [QSA]
RewriteRule ^blogs/.* blog.php [QSA]
RewriteRule ^entries/.* entry.php [QSA]

RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d

RewriteRule ^.*$ - [NC,L]

# MVC
RewriteCond %{REQUEST_FILENAME} !\.php$
RewriteRule ^(?:(.*?)(?:/|$))(.*|$)$ $1.php?r=$2 [QSA]

Forum (/live)

RewriteCond %{REQUEST_FILENAME} -f [OR]RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d

RewriteRule ^.*$ - [NC,L]

# Forum
RewriteRule ^threads/.* showthread.php [QSA]
RewriteRule ^forums/.* forumdisplay.php [QSA]
RewriteRule ^members/.* member.php [QSA]

Blog (/blog)

RewriteCond %{REQUEST_FILENAME} -s [OR]RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d

RewriteRule ^.*$ - [NC,L]

RewriteRule ^blogs/.* blog.php [QSA]
RewriteRule ^entries/.* entry.php [QSA]

Any ideas?

Thanks,
