    I am having a problem, my nav bar is stuck on user Logged In mode. I can't seem to get back to the /users/sign_in (/sign_up). The browser displays that i am already signed in when i try to route the Signed Up or Sign In Page. When i tried running the project on local but all i got back was the code below. HELP!!!

    Any help would be much appreciated.

    1st Browser safari (Default development browser)
    2nd Browser ( Test Development Browser) 

    Running this project on my local machine.

    <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false"><%= current_user.username%> <span class="caret"></span></a>

    If you could make the fonts of your code bigger, this series of tutorial would be near perfection. Perhaps you could do this in the next tutorial. Good job, though!
