This causes a problem:
.nav > li > a { display: block; }
which comes from bootstrap.css If you remove this CSS bit, it works correctly.
You can override this style in index2.php by adding display: inline; :
.navbar a, .navbar a:active, .navbar a:visited { color: #7f7f7f; padding-top: 35px; height: 90px; text-transform: uppercase; font-weight: bold; font-size: 14px; padding-bottom: 45px; display: inline; }
