I have a custom template in whmcs and I've edited header.tpl, homepage.tpl, and footer.tpl
The page looks perfect.
However, when I go to the shopping cart page, for example, that page does not use the template I used. The header and footer are there, but the core cart.php file does not use the template that I have created, and if I try to edit cart.php, I get a message saying that the file is 'corrupted'.
What am I doing wrong? It's the same way with so many other pages.... they won't let me touch them.
How do I get the contents of these files to show up within the context of the template that I have created?
Thanks in advance.
By the way, here is an example of what I mean:
Home page is fine:

But submit ticket page is not:
