Because WPML creates posts and pages for each language, comments from one do not appear on the other.
This plugin merges comments from all WPML translations of the posts and pages, so that they all are displayed on each other. 
Comments are internally still attached to the post or page they were made on.
It uses the <code>get_comments()</code> api call, which in some circumstances might not return all posts.
This is a fixed version of the no longer maintained WPML Comment Merging plugin:

Thanks to Simon Wheatley for contributing the fix.

On posts where comments are closed, the plugin will remove the text ‘Comments are closed.’ The plugin supports any languages/text domain, and will remove the text from themes and plugins.
Prerequisite: Since the plugin is <a href="https://codex.wordpress.org/Plugin_API/Filter_Reference/gettext" rel="nofollow ugc">filtering gettext</a>, your theme/plugin must be <a href="http://wp.smashingmagazine.com/2011/12/29/internationalizing-localizing-wordpress-theme/" rel="nofollow ugc">localized</a>.
