I’m also having this problem
I’m using the Magzimus theme so, like ChimpanzeeUK, every time the plugin is updated I edit disqus.php according to the instructions here: http://blogtechguy.com/1560/fixing-view-comments-in-disqus-plugin/. Otherwise the “View Comments” link is too large for the theme.
Any help would be appreciated.
I was getting the same message as well. Even though I was already at 2.8.2, I performed the upgrade procedure, and now the message is gone.
