Bootswatch theme not working correctly : <p>It's my first time working with ASP.NET, I'm trying to use a Bootswatch theme but when I try to use it the navigation bar at the top of the page turns into a weird drop-down menu.</p>

<p>Am I doing something wrong? I just replaced the current bootstrap.css with the new one from Bootswatch.</p>
