Q&A User Profile Dispaly Issue

I have installed the Q&A plugin and have a few questions.

1. On http://www.retireinthecaribbean.com it displays well but the user profile page does not appear. In other words, the url shows /user/admin for example but the profile isn’t there, just some other page. It might be a conflict with the theme? (WPCasa).

2. I hope I am doing something wrong on this next issue…. Do all new users get sent to the WP backend profile when they register upon asking a question??? It does this on twentytwelve too. I mean, isn’t this plugin completely frontend for Q&A users? Does a WP black topbar really display when a visitor logs in? I must be doing something wrong I hope!

Thanks again!
