one more thing i Want to redirect my Sign Up page to signup.php
how can i do that ?

Im using dreamhost.com as my host

my htaccess.dist file contents are

RewriteEngine On
RewriteBase BASE/

#uploaded files
RewriteRule ^(.*/)?files/$ index.php [L]
RewriteRule ^(.*/)?files/(.*) wp-content/blogs.php?file=$2 [L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule . - [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-.*) $2 [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(.*\.php)$ $2 [L]
RewriteRule . index.php [L]

htaccess.dist is a file included in the deafault distribution. It is there, so on install, it gets copied to make .htaccess with your install info.

Editing that file won't change a thing.

Was the install working before you made the redirect?
have you turned on "show hidden files" when you look at the files on the server? If you can't see the htaccess, that's probably why, because in my experience, if it can't make the htaccess fileon install, it bombs and doesn't work at all.

So go check that first.

yes i cant see any .htaccess file at all in my ftp !!
ohh !! thats the problem got it !!

so i need to make a new .htaccess file .. cuz accidentally i replaced it by making new .htaccess file

so what should be my .htaccess file contents now ? ?

It should look exactly like the htacces.dist, EXCEPT for this part:

RewriteBase BASE/

should be

RewriteBase /

The original htacces.dist, not the one you played with ^_^

wow !! Worked like a Charm !!
thnx for you valuable time

what if neither htaccess.dist or .htaccess has:
RewriteBase /

I'm getting 404 errors on any page but the root but as .dist doesn't have it, I'm confused if it should. That said, I added it and it didn't do anything; does it matter where in the htaccess I put it?

You should put RewriteBase / before any rewrite rules.
Also, htaccess.dist has RewriteBase BASE and .htaccess should have RewriteBase / (if you installed WPMU in domain root) or any other value if WPMU is elsewhere, but definitely not default BASE value.
