Hi there,
I am not sure about this case. I see that there is a Javascript error on my browser console when I visited the link you have provided:
That is an error happening on the embed.js file of the Disqus framework. I wonder if you used our extension for the Disqus comments? If not please try to use the plugin by going to Pro > Validate and scroll to find the plugin.
If you do use our plugin kindly get back to us with the URL/User/Pass of your WordPress dashboard using the Secure Note functionality of the post to follow up the case.
Thank you.
