Add to cart button is not working

Issue:  The add to cart button is not working after we enable the defer javascript extension

Solution:

Remove code

<!-- <script>

(function() {

  var _fbq = window._fbq || (window._fbq = []);

  if (!_fbq.loaded) {

    var fbds = document.createElement('script');

    fbds.async = true;

    fbds.src = '//connect.facebook.net/en_US/fbds.js';

    var s = document.getElementsByTagName('script')[0];

    s.parentNode.insertBefore(fbds, s);

    _fbq.loaded = true;

  }

  _fbq.push(['addPixelId', '903143773051497']);

})();

window._fbq = window._fbq || [];

window._fbq.push(['track', 'ViewContent', {

content_type: 'product',

content_ids: ['<?php echo $_product->getSku(); ?>'],

product_catalog_id: '800958149940258'

}]);

</script>
