I have been using this plugin for a few years and it has always performed very well.
2 weeks ago I noticed a problem on my blog and then it disappeared. Today it re-appeared. All the links to the comments are now "https" rather than http: I am using the shortcode and this code in the plugin:
<b><a href="%comment_link" rel="nofollow">%comment_author</a></b> has stated: <a href="%comment_link" title="%post_title" rel="nofollow"><i>%comment_excerpt</i></a><br>
I cleared my cache on the WP Super Cache, but it still appears as https links. Any idea why? No other site links are being rendered as secure http......
