This plugin was great at first. Now with the updates it simply broke my site so that even after I deactivated the plugin and deleted it, my site still does not work the way it did before. Now, even with the plugin gone, no one can comment on older posts no matter what I do to the settings. People can only comment on blog posts from after I deleted the plugin, which leaves me with hundreds of pages of content that no one can comment on in any way. If I had never used this plugin to start with I would have been much better off than I am now.
And when I posted my problem on the forum, the plugin author just automatically listed it as "resolved" and said to post to his website. When I did that I got no response on how to fix my now-broken blog.
