Login issues and top menu shortcode are not working

Hi, I installed the plugin at http://drummerboyhosting.com and almost everything is running great, I just have a couple of questions listed below:

1. When I try to log in as a client via the front end of wordpress by clicking on client area, I get logged in to the whmcs area and I see the portal theme, I no longer see the wordpress side of the website. Is that what’s supposed to happen?

1a. Even id I’m logged in when I go back to the front end of wordpress, and I click on client area, I’m asked to log in again.

2. The top menu shortcode: [wcp_menu] displays nothing at all.

Thanks in advance for your help with this matter!
