Here is a new installation of apache2 on a Ubuntu 12.04 machine (home user)
I am trying to start the service apache2 after creating a file in sites-available directory and enabling the website I am getting following error
user@ubuntu:/etc/apache2/sites-enabled$ service apache2 reload
* Reloading web server config apache2 /usr/sbin/apache2ctl: 87: ulimit: error setting limit (Operation not permitted)
httpd not running, trying to start
(13)Permission denied: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
Unable to open logs
Action 'graceful' failed.
The Apache error log may have more information.
[fail]
Now there I do not find any thing in apache log as such but posting here error.log

what is wrong with apache2 service that it is unable to start ....
sudo?sudo service apache2 reload?useralso explains why you don't see anything in the logs - the permissions on those log files don't permit that.
