Error 404 Multisite Manager

Thanks for your response.

Yes I have mod_rewrite Apache enabled and i have Options +FollowSymLinks actived and Allowoverride All too, every change on .htaccess affects to page.

I was all day configuring and changing Apache config. But i can´t enable for example Clean Url´s it was impossible for me. I tried all: http://drupal.org/node/15365

.htaccess

RewriteEngine on 

#file access
RewriteRule ^\w+/(modules|misc|files|themes|sites)(.*)$ ./$1$2 [L]

RewriteRule ^/(modules|misc|files|themes|sites)(.*)$ ./$1$2 [L]

#special php scripts
RewriteRule ^\w+/(update.php|install.php|index.php)(.*)$ ./$1$2 [L,QSA]

#site sub-section
RewriteCond %{REQUEST_FILENAME} ^/home/user/public_html/site/.*
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^\w+(/)?(.*)$ index.php?q=$2 [L,QSA]

The rest of file is .htaccess base of drupal. I attempt with #RewriteBase / and RewriteBase /

sites/default/settings.php

$db_url = 'mysqli://username:password@localhost/database';
$db_prefix = 'drupal_';
$base_url .= "http://localhost";

$requri = explode('/', request_uri());
if (sizeof($requri) >1 && $requri[1]=='site' && $requri[2] != '') {
   $my_site_base = $requri[2];   
   #this will be the database shared between the main site and the shared sites
   $db_url = 'mysqli://username:password@localhost/database';
   $db_prefix = $my_site_base."_";
   $base_url .= "http://localhost/site/$my_site_base";  // NO trailing slash!
}

I hope this information will be enough. Thanks!

Thanks I will study cleanURLs now. I think same, when i get cleanURLs i will resolve my problem.

This point!!!! (".") I´m all days making changes adding for example "/~user/" to url base and making several changes and i let it, error. But i removed this "." from $base_url and the problem persist.

I don´t understand what do you said with works on /var/www/localhost/. In any case my base directory is /var/www/htdocs

Do you said me that i can move all the directory without problem there?

Thanks!

Edit:
Yes i find the problem. It was this sentence:

RewriteBase /

I tried to enable it but I needed to add /~user/

RewriteBase /~user/

I tried this too but this time i moved this line to the begin of the sentences that rewrite the url for Multisite_manager.

Thanks! I hope that it will help to another one!
