Hello.  I just stumbled across this platform a few days ago and I am very excited to try it out.  I successfully installed version 12.0.0-B2; the home page loads and I am able to login to the back-end (studio).  When I go to the home page as a visitor and click on the "join now" button or the login button, neither works.  More specifically, when either link is clicked, the home page simply reloads and so neither link takes me anywhere.  What am I missing?
