Pb saving a page

Hi,

I have a problem with kwiki: when saving a page that I have edited. I get this error message:

-------

Can't open file 'database/PersonalPage' for output:

I think this comes from a problem with my server configuration, but I'm not sure.
In the file /etc/httpd/conf/httpd.conf of my machine, I have added this:

Alias /kwiki/ "/var/www/cgi-bin/atollkwiki/"
<Directory /var/www/cgi-bin/atollkwiki/>
     Order allow,deny                                                       
     Allow from .inria.fr
     AllowOverride All
     Options ExecCGI                                                        
     AddHandler cgi-script .cgi                                             
</Directory>

Do you know what is wrong with my configuration ? 
The thing is I can access the kwiki, the kwiki looks good with the stylesheet and all and I can edit a page, 
but when I click on the save button, I get this error. I suppose there is a problem of path somewhere 
and the directory database/ cannot be found.

Best regards,
IC
