Problem with latest version of WordPress and/or Woocommerce

Since upgrading to WordPress 4.8.3 or possibly WooCommerce 3.2.2 (I updated both at the same time) I have the following line of code appearing on my shop page:

#disqus_thread {display:none;} .dcl-disqus-thread {display:none;}

I’m assuming there’s an incompatibility somewhere so would be really grateful if you could look into it.

Best wishes,

Dave
