Livefyre is not working on AEM 6.4

[#1]

We have migrated from AEM 6.2 to AEM 6.4 and upgraded LiveFyre packages as per Adobe's documentation.
It's working as expected on Author environment but I see issues on Publisher environments. Where ever we use LiveFyre comments the entire page is broken and does not show any content on the page. I don't see any errors in the browser console

Do we need to install any service packs for livefyre?

Here are the Error logs
