How to remove indicators from owl carousel

Since you are using OwlCarousel version 1, please check out their documentation. This also says pagination (dots) can be turned off with:

pagination: false,

The dots: false, is for version 2. See this GitHub issue which is asking the same question.

Try as below:

$('.owl-carousel').owlCarousel({
  nav: false,
  dots: false,
.....
..

<pre>
<code>

    <script type="text/javascript">
        $(document).ready(function(){
            $('.owl-carousel').owlCarousel({
                dots: false,
            });
        });
    </script>

</code>
</pre>
