Nothing shows up on the page I created

I've gone through the setup of WHMCS on my site, but whenever I use any of the links, it doesn't show anything, just the page I created with the title and nothing else.

Here are two examples:

URL created from the encoder tool:
http://book-tour.com/client/portal/contact.php/?

URL using the information given on the setup page:
http://book-tour.com/client/portal/contact.php

With the second one, the pagename is client & the endpoint is portal.
