I'm asking so we can fix the actual redirects for everyone.

You tried adding these rules?

    # configuration rules
        # legacy css being handled separate for performance
        location = /css\.php {
                rewrite ^ /core/css.php break;
        }
 
        # make install available from presentation
        location ^~ /install {
                rewrite ^/install/ /core/install/ break;
        }
 
        # any request to not existing item gets redirected through routestring
        location / {
                if (!-f $request_filename) {
                        rewrite ^/(.*)$ /index.php?routestring=$1 last;
                }
        }
 
        # make admincp available from presentation
        location ^~ /admincp {
                if (!-f $request_filename) {
                        rewrite ^/admincp/(.*)$ /index.php?routestring=admincp/$1 last;
                }
        }
        # process any php scripts, not found gets redirected through routestring
        location ~ \.php$ {
                # handles legacy scripts
                if (!-f $request_filename) {
                        rewrite ^/(.*)$ /index.php?routestring=$1 break;
                }
        }

And they weren't working?
