Laravel 5 Pagination CSS Breaking

Question

I'm using Laravel 5 and Bootstrap 3.3.4

So I have the following code in my controller:

$articles = Newsarticles::paginate(10);
return view ('news',compact('articles');

Then in my view I have:

@foreach($articles as $article)

<article>
    <h2>
        <a href="{!! action('DynamicPages@show', [$article->slug]) !!}">{!! $article->headline !!}</a>
    </h2>
    <div class="body">
        {!! substr($article->article,0,500) !!}
    </div>
</article>

@endforeach

{!! $articles->render() !!}

When I run this, the pagination links at the bottom of the page come out just fine and look as they should do. However, if I change the controller to :

$articles = Newsarticles::orderBy('artdate','DESC')->paginate(10);

my pagination links come out like this:

«
1
2
3
4
5
6
»

How can one small adjustment in the code break the css?
