Links not working in q & a plugin

Hello, when asking or answering a question, the users are unable to include links using the TinyMCE link button. When you add a link to the pop up box and click 'add link' it just refreshes the page and nothing happens. Any idea on what I can do to correct it?

Here's a link to my ask question page so you can see what I mean http://www.blackhairinformation.com/community/questions/ask/
