Bootstrap 3 navbar links not working

I have a navbar with links in it. The "brand" link is working but nothing in the ul does. I have read things about e.preventDefault(); being a problem when it is with the $('ul.nav > li').click(function (e) {. I also have read where it has something to do with the z-index. I don't find any of those to be the case (unless I couldn't find it embedded in a js file loaded with the application and not residing in my assets folder).

What could cause this?

I'm not sure whether it would be in the css or the js file. Also, the toggle works fine, it's just the active links.

While inspecting elements, I found an error... TypeError: undefined is not an object (evaluating '$(target).offset().top') which points to this part of the jquery.js file.

//smooth scroll
$('.navbar-nav > li').click(function(event) {
    event.preventDefault();
    var target = $(this).find('>a').prop('hash');
    $('html, body').animate({
        scrollTop: $(target).offset().top // this line here
    }, 500);
});

However, when I look at the jquery documentation (http://api.jquery.com/event.preventdefault/), it say, "If this method is called, the default action of the event will not be triggered.". So it seems that might be the case, but I'm not sure how to get around it.

I had the very same problem caused by Javascript. Just give the a link an ID and the OnClick function lets you navigate smoothly.

HTML :

<div class="navbar-collapse collapse " id="templatemo-nav-bar">
    <ul class="nav navbar-nav navbar-right" style="margin-top: 40px;">
        <li class="active"><a href="index.htm">HOME</a></li>
        <li><a  id="aboutus">ABOUT US</a></li>
        <li><a id="clients">OUR CLIENTS</a></li>
        <li><a id="products">PRODUCTS</a></li>
        <li><a id="contact">CONTACT</a></li>
    </ul>
</div><!--/.nav-collapse -->

JS :

document.getElementById("aboutus").onclick = function () {
    location.href = "aboutus.html";
};

To make an external link (all links that are not anchors) work inside the nav just add the class attribute with the value "external" inside youre <a> element. <a href="foo.html" class="external">Foo</a> . This helped me while using jquery.nav.js.

I am not sure what is happening with your code, but if there are js event handlers attached to your links you can try to remove handlers on links using:

$(document).ready(function () {
    $("#bs-example-navbar-collapse-1").find("a:not(.dropdown-toggle)").off("click").off("mousedown");
});

Update
Try to manually send user to link, but this is not the right way. You can use the following code to verify are there any mask layers hiding the link (if nothing happened this time also than there are layers).

$(document).ready(function () {
    $("#bs-example-navbar-collapse-1").find("a:not(.dropdown-toggle)").on("click", function (e) {
         e.preventDefault();
         window.location = $(this).attr("href");
    });
});

Update 2
The problem is in your smooth scroll. You dont have hash property in your links.
Change your code to:

$('.navbar-nav > li').click(function(event) {
    if($(this).parent().parent().is("#bs-example-navbar-collapse-1")) return;
    event.preventDefault();
    var target = $(this).find('>a').prop('hash');
    $('html, body').animate({
        scrollTop: $(target).offset().top // this line here
    }, 500);
});
