Hello Kelvin and thanks for the detailed reply - it really does help in finding suitable solutions.
Please try and follow this comprehensive and complicated reply as it may take repeated reads to follow what I have suggested, especially with regard to the alternative configuration, as it will free up a sub-domain for future use.
If I have understood what you are trying to achieve then the following configurations may be what will solve your current 3 web site configuration dilemma - but the alternative configuration below is the preferred, if it suits your needs.
1. Main X10 Hosting domain as currently defined in your AMP:
sfc.x10hosting.com
Site Files:
public_html/index.html
(index file extensions may be wrong but use the correct index file extensions for your respective sites).
URI:
http://sfc.x10hosting.com/
Web Site Title:
Speed Forum Challenge
2. Addon Domain to your X10 Hosting's main domain - created in cPanel and uses up 1 sub-domain and 1 add-on domain from your allocation:
whsprojectcitizen.org
Site Files:
public_html/projectcitizen/index.php
URI:
http://www.whsprojectcitizen.org/
Web Site Title:
Project Citizen
3. Sub-domain of your main domain - created in cPanel:
(
Is this duplication really needed now as it would seem to be a waste of an allotted sub-domain?).
projectcitizen.sfc.x10hosting.com
Site Files:
public_html/projectcitizen/index.php
URI:
http://projectcitizen.sfc.x10hosting.com/
Web Site Title:
Project Citizen (
Duplicate)
4. Sub-domain of your main X10 Hosting's main domain - created in cPanel:
(
See Note below for directory information).
clans.sfc.x10hosting.com
Site Files:
public_html/clans/index.php
URI:
http://clans.sfc.x10hosting.com/
Web Site Title:
World Cup Clan Site
The above configuration should just about use up all your allotted sub-domains and add-on domains in cPanel.
---------------------------------
An alternate configuration would be to follow
this tutorial to replace the X10 Hosting main sub-domain with your owned domain - which in my opinion looks more professional and easier to remember the addresses.
Then just add your other sub-domains to your main owned domain, which will leave you with a spare sub-domain in cPanel.
1. Main X10 Hosting domain as defined in your AMP:
whsprojectcitizen.org
Site Files:
public_html/index.php
URI:
http://www.whsprojectcitizen.org/
Web Site Title:
Project Citizen
2. Sub-domain to your X10 Hosting's main domain - created in cPanel:
sfc.whsprojectcitizen.org
Site Files:
public_html/sfc/index.html
URI:
http://sfc.whsprojectcitizen.org/
Web Site Title:
Speed Forum Challenge
3. Sub-domain of your main X10 Hosting's main domain - created in cPanel:
clans.whsprojectcitizen.org
Site Files:
public_html/clans/index.php
URI:
http://clans.whsprojectcitizen.org/
Web Site Title:
World Cup Clan Site
Note:
If you want to use
clans as a sub-domain then you will have to move the files from the
worldcup directory to the cPanel created
clans directory after creating the sub-domain, or alternatively you can create a subdomain called
worldcup.
The above keeps it simple as you have only used 2 sub-domains of the 3 allotted and frees up a spare sub-domain for future use.
As you have discovered, it is not possible to add-on a domain to a sub-domain of your X10 Hosting's main sub-domain.
Also remember it may take up to 24 hours for any changes to your hosting configuration to filter down to the server and possibly longer to propagate the Internet DNS system.
I hope this will be of help to you.
Regards and good luck with your sites,
Rocky
