Subdomain of Parked domain suddenly not working

[ensermo]

Dear Users/Support,

I have a domain: maindomain.com
On top of that domain I parked the domain: parkeddomain.com

This was working without problems.
After some time I went in CPanel and went to "Sub Domain Maintenance".

There I added two subdomains

forum.maindomain.com and forum.parkeddomain.com

Both where redirected to http://maindomain.com/forum/

These subdomains have been working for some time without problems.
Suddenly about a week ago the subdomain of parkeddomain.com stopped working.
(The subdomain of maindomain.com is still working)

My current WHM/CPanel is
WHM 10.6.0 cPanel 10.8.0-S59
RedHat 9 i686 - WHM X v3.1.0

I have tried solve the problem: (changed domainnames and ip's)

1.in /etc/httpd/conf/httpd.conf the entries are there

<VirtualHost 123.123.123.123>
BytesLog domlogs/forum.maindomain.com-bytes_log
<IfModule mod_php4.c>
php_admin_value open_basedir "/home/maindoma/:/usr/lib/php:/usr/local/lib/php:/tmp"
</IfModule>
ServerName forum.maindomain.com
ServerAlias www.forum.maindomain.com
ServerAdmin wwwadmin@maindomain.com
DocumentRoot /home/maindoma/public_html/forum
CustomLog domlogs/forum.maindomain.com combined
ScriptAlias /cgi-bin/ /home/maindoma/public_html/forum/cgi-bin/
User maindoma
Group maindoma
</VirtualHost>

and

<VirtualHost 123.123.123.123>
ServerAlias www.forum.parkeddomain.com
ServerAdmin webmaster@forum.parkeddomain.com
DocumentRoot /home/maindoma/public_html/forum
BytesLog domlogs/forum.maindomain.com-bytes_log
ServerName forum.maindomain.com

2. The file /var/cpanel/users/maindoma exists.
BWLIMIT=5242880000
DNS=maindomain.com
FEATURELIST=default
IP=123.123.123.123

MAXADDON=5

DNS7=test1.maindomain.com
XDNS1=parkeddomain.com.sub.maindomain.com
XDNS2=test1.parkeddomain.com
DNS8=forum.parkeddomain.com

3. I tried running the command
/scripts/updateuserdomains
and
/scripts/updateuserdomains2

Nothing happens.

4. Restared Apache, DNS etc.

Internally (between servers on the cluster) I am able to ping everything but outside not.

This just stopped working all of a sudden.

Any ideas?

Thank in advance.

What is the error that you get while browsing forum.parkeddomain.com

[ensermo]

It isn't found. Timed Out. Like the DNS isn't set. But it is allright in the DNS.

[Murtaza_t]

Well can you ping forum.parkeddomain.com from your computer, If no then it has to be a DNS issue and not Cpanel issue.

Try recreating the park and its subdomain.

[ensermo]

I deleted and recreated the subdomain yesterday evening. Today I tried loading the webpage and now I am seeing the following error.

url: http://forum.parkeddomain.com

Forbidden
You don't have permission to access / on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
Apache/1.3.33 Server at forum.parkeddomain.com Port 80

Seems like something went wrong in the httpd.conf I think.. or is it somewhere else?

[Murtaza_t]

Does the park domain work fine... or it is just the subdomain.

It would be more helpful if you could paste the virtualHost Entry for the prakdomain

[ensermo]

The parked domain is working perfectly. When putting parkeddomain.com in the browser it will automatically give the output of the site but still show parkeddomain.com in the url (even when clicking links as long as they are relative ./link.htm ./contact.htm etc)

This is the only place where parkeddomain.com is found in /etc/httpd/conf/httpd.conf

<VirtualHost 123.123.123.123>
ServerAlias www.maindomain.com maindomain.com
ServerAdmin webmaster@maindomain.com
DocumentRoot /home/maindoma/public_html
BytesLog domlogs/maindomain.com-bytes_log
<IfModule mod_php4.c>
php_admin_value open_basedir "/home/maindoma/:/usr/lib/php:/usr/local/lib/php:/tmp"
</IfModule>
ServerName www.maindomain.com
ScriptAlias /cgi-bin/ /home/maindoma/public_html/cgi-bin/
ServerAlias parkeddomain.com www.parkeddomain.com
ServerAlias otherdomain.cc www.otherdomain.cc
User maindoma
Group maindoma
CustomLog domlogs/maindomain.com combined
</VirtualHost>

And this one

<VirtualHost 123.123.123.123>
ServerAlias www.forum.parkeddomain.com
ServerAdmin webmaster@forum.parkeddomain.com
DocumentRoot /home/maindoma/public_html/forum
BytesLog domlogs/forum.parkeddomain.com-bytes_log
ServerName forum.parkeddomain.com
<IfModule mod_php4.c>
php_admin_value open_basedir "/home/maindoma:/usr/lib/php:/usr/local/lib/php:/tmp"
</IfModule>
<IfModule mod_php5.c>
php_admin_value open_basedir "/home/maindoma:/usr/lib/php:/usr/local/lib/php:/tmp"
</IfModule>
User maindoma
Group maindoma
CustomLog /usr/local/apache/domlogs/forum.parkeddomain.com combined
ScriptAlias /cgi-bin/ /home/maindoma/public_html/forum/cgi-bin/
</VirtualHost>

It all seems ok to me.
- DNS for maindomain.com, parkeddomain.com point to the correct ip (123.123.123.123)
- There is a A record in the DNS entry for forum of parkeddomain.com
forum 14400 A 123.123.123.123
www.forum 14400 A 123.123.123.123
- The Virtualhost is correct for forum.parkeddomain.com
- The DocumentRoot for forum.parkeddomain.com points to the correct path
- The users exist and own the directories.

Hmm.. Did I miss something?

**** Edited ***
There is a .htaccess file in
/home/maindoma/public_html/forum
with

RewriteEngine on
RewriteCond %{HTTP_HOST} ^forum.maindomain.com$ [OR]
RewriteCond %{HTTP_HOST} ^www.forum.maindomain.com$
RewriteRule ^(.*)$ http://maindomain.com/forum/$1 [R=301,L]

Could that be it?

[Murtaza_t]

Yup maybe it is the .htaccess file as it has the REWRITE RULE set..
Just rename it as .htaccess.bak.. I think that should fixed..

And Parked domains are frame forwarders hence no matter what URL you are visiting on the main domain it will show only http://parkdomain.com in the browser.

[ensermo]

Murtaza_t thanks for helping me on this one.
I finally solved it by putting this in the .htaccess file

RewriteEngine on
RewriteCond %{HTTP_HOST} ^forum.mainsite.com$ [OR]
RewriteCond %{HTTP_HOST} ^www.forum.mainsite.com$
RewriteRule ^(.*)$ http://mainsite.com/forum/$1 [R=301,L]

RewriteCond %{HTTP_HOST} ^forum.parkedsite.com$ [OR]
RewriteCond %{HTTP_HOST} ^www.forum.parkedsite.com$
RewriteRule ^(.*)$ http://mainsite.com/forum/$1 [R=301,L]

Even though the question remains... how did it break in the fist place!
