title: Conflict with WPBakery Page Builder and blockUI - Defaults not defined woo-commerce checkout and cart pages
body: <p>I am having an issue where the checkout in woo-commerce is not working because of  $.blockUI.defaults not being defined, if I disable WPBakery it works but other aspects of the site do not work of course.</p>
  
  <p>It also errors on blockUI in the cart when trying to update it.</p>
  
  <p>Any help would be amazing!</p>
  
  <p>I have disabled all plugins and had no there conflicts except WPBakery Page Builder.</p>
  
  <p>Thought it was the older version of jQuery so have updated to latest.</p>
  
  <p>Unfortunately can't find anything about this issue.</p>
  
  <p>A product can be added to cart here:</p>
