Tht was silly of me not to check if rewriteEngine was on, but I knew that I had to restart apache as soon as I change httpd.conf !
So I confirme, I did restarted apache .
the fact is that .htaccess in /wpmu start with:
#php_flag register_globals 0
#php_flag display_errors 0
RewriteEngine On
RewriteBase /
So actually "RewriteEngine On" was already there.
Now I added it to the directory directive in httpd.conf, and it looks ok at least for that directive, now if I comment it in .htaccess , that's the second directive in .htacces (RewriteBase) which is refused :
[Tue Jun 06 10:12:04 2006] [alert] [client 157.159.50.197] /var/www/html/wpmu/.htaccess: RewriteBase not allowed here
apparently, apache doesn't accept any rewrite module directives in a .htaccess. However I did put allowOverride all in the / directory wich is my DocumentRoot !
DocumentRoot "/var/www/html/wpmu"
<Directory />
Options +Includes +FollowSymlinks -Indexes
AllowOverride All
RewriteEngine On
</Directory>
What am I doing wrong ? is there any installation doc somewhere, appart from http://mu.wordpress.org/download/ which is very minimal ! reading it, I though that unzipping the wpmu.zip and starting the web browser would be enough. I first had the email that never appeared (after the "congratulations etc ...") , so I got inside the mysql database to reset the admin password as I nerver got it from mail, and now I'am stuch with that rewriteengine error?
Please help, thanks .
PS: I've read http://photomatt.net/2003/10/10/wildcard-dns-and-sub-domains/, but don't really see a relation to my problem !?
