Change of default page in cpanel/WHM

In WHM, look for "Account Functions" and choose "Skeleton Directory". This will show you where your directory is. Anything you add to your skel directory will automatically be added to the users directory when you create a new account.

If you place a default HTML page within the "public_html" sub-directory then it will be included within the public_html directory of the user's new account upon creation.

Example paths:

/root/cpanel3-skel
/root/cpanel3-skel/public_html
/root/cpanel3-skel/public_html/index.html
