Cacti on opensuse 12.2 web server

Hi
I have installed several instance on my apache web server running under opensuse 12.2

these arent under /srv/www/htdocs

I want to try cacti for futur use and so i have installed cacti

cacti is installed by rpm under /srv/www

so i run yast hhtp apache web configuration and create a virtual web named cacti

at this time i saw cacti is running but the other web site began unavailables !!

If i delete cacti virtual web my other web site are visible

my is default server.conf is :

DocumentRoot "/srv/www/htdocs"

<Directory "/srv/www/htdocs">
 Options None
 AllowOverride None
 Order allow,deny
 Allow from all
</Directory>

Alias /icons/ "/usr/share/apache2/icons/"

<Directory "/usr/share/apache2/icons">
 Options Indexes MultiViews
 AllowOverride None
 Order allow,deny
 Allow from all
</Directory>


ScriptAlias /cgi-bin/ "/srv/www/cgi-bin/"

<Directory "/srv/www/cgi-bin">
 AllowOverride None
 Options +ExecCGI -Includes
 Order allow,deny
 Allow from all
</Directory>

<IfModule mod_userdir.c>
 UserDir public_html
 Include /etc/apache2/mod_userdir.conf
</IfModule>

Include /etc/apache2/conf.d/*.conf 



my cacti.conf under vhosts.d is

<VirtualHost *:80>
    ServerAdmin bga.lambert@free.fr
    ServerName caci.local
    DocumentRoot /srv/www/cacti
    # if not specified, the global error log is used
    ErrorLog /var/log/apache2/cacti-error_log
    CustomLog /var/log/apache2/cacti-access_log combined
    HostnameLookups Off
   # needed for named virtual hosts
    UseCanonicalName Off
    # configures the footer on server-generated documents
    ServerSignature On
##
   
    <IfModule mod_userdir.c>
    userDir public_html
    include /etc/apache2/mod_userdir.conf
    </IfModule>
    <Directory "/srv/www/cacti">
  Options Indexes FollowSymLinks
AllowOverride None
Order allow,deny
Allow from all
     </Directory>

</VirtualHost>

Any idea ?

Try configuring cacti on port 8080.
