Because your angular script tags are in the html head, there is slight chance that not all modules are done loading when they are being used.

According to Where should I put <script> tags in HTML markup?, you have two options here:

1. Add a defer to your script tags in the head, which might not work for all browsers:

<script src="bower_components/jquery/dist/jquery.js" defer></script>
<script src="bower_components/angular/angular.js" defer></script>
<script src="bower_components/bootstrap/dist/js/bootstrap.js" defer></script>
<script src="bower_components/angular-ui-router/release/angular-ui-router.js" defer></script>

2. Put them at the bottom of your body. This will work for all browsers.

    ...

    <script src="bower_components/jquery/dist/jquery.js" defer></script>
    <script src="bower_components/angular/angular.js" defer></script>
    <script src="bower_components/bootstrap/dist/js/bootstrap.js" defer></script>
    <script src="bower_components/angular-ui-router/release/angular-ui-router.js" defer></script>

    <!-- build:js({.tmp,app}) scripts/scripts.js -->

    <script src="scripts/app.js"></script>
    <script src="scripts/controllers/main.js"></script>
    <script src="scripts/controllers/register.js"></script>
    <script src="scripts/app.config.js"></script>
    <!-- endbuild -->
    </div>
</body>

Thank you, But I tried that first and didn't work :(, then I added them to the head. — becki, Aug 31 '15 at 17:50
@James: An external script attributed with `defer` will not be executed until the page has finished loading. See also [The HTML Script Element](https://developer.mozilla.org/de/docs/Web/HTML/Element/script). — frhd, Aug 25 '16 at 11:41

Switching to a different library is not the answer to the original problem. – frhd Aug 31 '15 at 07:54
It can be a pragmatic solution, though. – Risadinha Aug 31 '15 at 08:36

It can be, but in this case, at least a reason should be given as to _why_ the library should be swapped. This is a major change, and I assume it's hard to find arguments against using `ui-router`. – frhd Aug 31 '15 at 08:41
