Hello,

As I said in the title I cant access one of the sites I am hosting by www.domain.com
The only way it works is by typing domain.com...
Any clue how to fix that in cpanel or whm?

Thanks

Shouldn't this be in the tech help section??

Anyway check your DNS and the A record pointing.
Alternatively if its a new doman, maybe the Nameservers have not resolved yet.

Check the httpd.conf file to make sure that there is a ServerAlias entry for both domain.com and www.domain.com

most likely you do not have the www record setup right in your DNS or not replicated as mentioned before.... Check with your provider

If this is a relatively new account, its probably a DNS caching issue with your ISP and you just need to wait a day or two for it to work itself out. What is the domain name, so that we can check it for you?

Pretty much as the others said, check your DNS records;
Name - Type - Value
@ - A - 123.123.123.123
* - CNAME - domain.com.

Replace 123.123.123.123 with your site's IP address
Replace domain.com with your domain name (without leading www) - note that the . at the end is IMPORTANT

The * means that any prefix will direct to your site; e.g. ftp, mail, etc.
To limit it to specific prefixes then simply replace * with www or whatever

The * is an excellent way of creating dummy sub-domains as any prefix will be directed to your default directory. With some judicious scripting you can check what the prefix used was and server different content as appropriate; great for social sites as you can let people use <username>.domain.com to go straight to their personal home page.

Ping www.domain.com

If it pings to the same IP as domain.com, then check httpd.conf for a server alias. If not, then the DNS needs to be updated, with www as a name to domain.com
