In Sharing, the Start button remains grayed out (never turning to Stop).

In teminal this is the report
[Me-Computer:/usr/sbin] ra% sudo apachectl restart
/usr/sbin/apachectl restart: httpd not running, trying to start
httpd: bad user name nobody
/usr/sbin/apachectl restart: httpd could not be started
[Me-Computer:/usr/sbin] ra%

I recently edited httpd.conf to try to set up a blog site. I backed up the old unedited version and replaced it after giving up on the installation. The changes I made seem to be back to their original settings, but now I`m not able to access my Intranet in the Sites folder.
