Classifieds Plugin: When click on the name of the person who posted takes me to the home page

Hi this is the link I am talking about:http://www.paidinstyle.com/classifieds/
When I am on this page and click on the name of the person who posted takes me to the home page, same thing happens when you go inside the clasifieds ad and click on Posted by: Name...I also noticed when you go to member profile and click "classifieds" it also takes you to the home page. I wonder if there is wrong with my settings or is it a bug?
Please, help
