WordPress MU

In htaccess.dist which has a vew variable in which are replaced when creating the .htaccess there's also HTTP_HOST used which will look quite strange in every recent installation.

So, edit your .htaccess and replace
RewriteCond %{HTTP_http://www.example.org} ^www\.(.*)
RewriteRule ^(.*) http://%1/$1 [R,L]
with
RewriteCond %{HTTP_HOST} ^www\.(.*)
RewriteRule ^(.*) http://%1/$1 [R,L]

Thanks, i've done the modification, but now i've a new problem rewrite rules are working for wp-login.php the first time, and after login (with correct u/p !) i'm back on the login page...
Bordel ! (f*ck) is there some one to help me !
Thanks
