Livefyre is not working on AEM 6.4

[prince233]

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

Please paste the beginning and end of the error to show the exception.

Also, is there a "Caused by" later in the error?
