This is my custom WHMCS page's content

I used the code found here.

I put that code into a file named:

mypage.php, which resides in the root directory (where my WHMCS is installed).

Now, I can write HTML into the file named:

mypage.tpl, located in the templates/six/ directory. Any HTML I save into that file, will be displayed on my new custom page.
