owncloud server

Hi
I installed owncloud server in my fedora18, it was working find until I modified the /etc/httpd/conf.d/system-config-httpd.conf without making a backup...
now I cant start my httpd.service

in the /etc/httpd/conf/httpd.conf when I comment the last line (which include the conf.d/ repertory)
my httpd service work but I just get:



Index of /

owncloud/


when opening 127.0.0.1 in a browser ( before I would get a page where I could log in and use owncloud).
And when I click on the owncloud/ link I get:

printPage(); exit; } ?>

t( 'Access forbidden' ); ?>

I have tried to look for the system-config-httpd file unmodified for countless hours of research but without any succes...

any help would be appreciate
