Starting apache fails (could not bind to address 0.0.0.0:80)

Question

Update: Already fixed, it seems that one of VirtualHosts configurations files was wrong in sites-enabled.

I have Ubuntu 11.10

When I run the command to start

Answer 1

What I would do is simply check if the following is set in your /etc/apache2/sites-available/your-domain-name.com.conf

SSLEngine on 
SSLCertificateFile /your/path/to/your-domain.com.crt
SSLCertificateKeyFile /your/path/to/your-domain.com.key
SSLCACertificateFile /your/path/to/your-domain.com.ca-bundle

and there aren't any mistyped directories or anything else that would not supposed to be in your .conf file. It did the trick for me as re-starting and killing the processes did not help at all. It did not start anyway.
