subdomain redirecting to root domain

All our subdomains *.domain.com are redirecting to domain.com/index.php.

Checked htaccess files in all subdomains for such a rule, no such.
It could be that the third-party script we use does something like this due to some misconfiguration, but if that was the case, new blank subdomains wouldnt redirect to root.

This among other things, is what the httpd.conf has:

Code:

<VirtualHost x.x.x.x:80>
   ServerName domain.com
   ServerAlias [url]www.beta.domain.com[/url] [url]www.test.domain.com[/url] [url]www.domain.com[/url] test.domain.com beta.domain.com
   DocumentRoot /home/user1/public_html
   ServerAdmin [email]webmaster@domain.com[/email]

1.
Does this explain anything - maybe since all subdomains point to the root public_html, it works that way?
If that's what is wrong, then how do I fix it - given that editing the httpd.conf file is not to be done?

The beta subdomain was merely pointing to the directory /home/user1/public_html/beta/
Is this a case of "addon" subdomain being mapped incorrectly as a "user" subdomain?

2.
When i tried deleting and re-creating the beta subdomain to point to /home/user1/public_html/beta from CPanelX - deletion looked successful at first,
but on attempting to create it again, it said "domainadmin-exists: beta.domain.com"

3.
I recently did a rebuild of EasyApache to enable mod_security, mod_deflate, mod_usertrack and disable frontpage extensions.

Is there some post-build process needed to reconfigure Apache ?

Related question: Is there a simple tutorial explaining virtual hosts + subdomains ?
The Apache manual isn't the easiest and my Google skills are failing me on this one.

Thanks in advance,

Thanks for a quick reply!

I know editing of httpd.conf isnt supposed to be done. Upon looking around I found this:
http://forums.cpanel.net/f5/remove-serveralias-virtualhost-170106.html
Is this the way to remove the serveraliases?
That one tells about this path:

Code:

/var/cpanel/userdata/username/subdomain.domain.com

This one: Daily Tech Tip: Removing a stray domain from a cPanel account « Brandon's Blog
shows a different path:

Code:

/var/cpanel/users/USERNAMEHERE

So which one?
Thanks again,
Dave.

 

Hi,
I tried out all the above steps (exact order) but the ServerAlias line in /usr/local/apache/conf/httpd.conf is the same - that is the test and beta subdomains are configured as aliases of the main domain.

However, I added another test domain, say test2, from cPanel X, which is working perfectly so far.

I have saved the current working httpd.conf. So if anything breaks later on, I hope I can just replace this httd.conf into the proper directory ( is it /etc/httpd/conf/ or /usr/local/apache/conf/ ? ) and get it to work.

We dont really need any more domains or subdomains if a test domain works well, so I'm not likely to do any more changes to domain configuration, even indirectly. Hopefully!

Obviously this is a dirty hack and far from the solution, but at least it will keep the test site running for work.

Thanks again for all the replies.
