WHMCS Integration links don't stay on WordPress page

Two questions about WHMCS Integration

1) Why does clicking Domain Checker or Order take the user off my site and into the old portal? That's not happening for Downloads, Announcements or Knowledgebase:

http://www.nocohosting.com/client-portal/whmcsportal/

2) Clicking any of the links that require login take the user off my site and to the old portal's login screen:

https://www.nocohosting.com/whmcs/serverstatus.php

My setting for Remote Host:
http://www.nocohosting.com/whmcs/

This is the same as what's in URL in WHMCS System settings. Help, please?
