[Mediawiki-l] Upload Problem

[Alessandra]

Hi all,

I use mediawiki 1.15.1 and I add option about 'delete' "/index.php"
from url, so that:
1) I added this lines into LocalSettings.php:
    $wgArticlePath = "/$1";
    $wgUsePathInfo = true;
2) and I created .htaccess into /path/wiki/:

RewriteEngine On

 # Don't rewrite requests for files in MediaWiki subdirectories,
 # MediaWiki PHP files, HTTP error documents, favicon.ico, or robots.txt
 RewriteCond %{REQUEST_URI} !^/(stylesheets|images|skins)/
 RewriteCond %{REQUEST_URI} !^/(redirect|texvc|index).php
 RewriteCond %{REQUEST_URI} !^/error/(40(1|3|4)|500).html
 RewriteCond %{REQUEST_URI} !^/favicon.ico
 RewriteCond %{REQUEST_URI} !^/robots.txt
 RewriteCond %{REQUEST_URI} !^/cgi-bin/download/upload_user.pl

 # Rewrite http://wiki.example.com/article properly, this is the main rule
 RewriteRule ^/(.*)$ /index.php/?title=$1 [L,QSA]

With this configuration, http://genomics.cribi.unipd.it/Special:Upload exists:
1) I can edit it, but when I click button 'Upload file', it doesn't
work and it only reloads Special:Upload page
2) if I comment this line into LocalSettings.php:
#    $wgArticlePath = "/$1";
then http://genomics.cribi.unipd.it/Special:Upload works.

How do I do to keep short url with Special:Upload running?
Can you help me about it?

Best,
Alessandra.
