This blog post should give you some hints on where to look for stuff: http://dmytroduk.com/techblog/disqus-for-episerver-8
I'm trying to install Disqus plugin to my epi project and get this:
Unable to find a version of 'EPiServer.CMS.TinyMce' that is compatible with 'EPiServer.DynamicContent 1.0.1 constraint
I'm not able to install DynamicContent too.
EPiServer.CMS.TinyMce installed version : 2.4.0
rather than that issue:
1- User wants to like the post/comments for the content . is it doable by Disqus?(both like and comment)
2- Is there any other plugin for commenting?
DynamicContent is depricated https://world.episerver.com/documentation/developer-guides/CMS/dynamic-content/
However, Disqus is really easy to integrate using universal code.
DISQUS is a very popular hosted comment system that makes it very easy to add comment functionality to new or existing sites. It takes care of spam, security (blacklists, whitelists), moderation, mobile and social media support and more.
