   YARPP was working very well. However, after automatically upgrading YARPP, I receive the following error after failed attempt to activate plugin:

   "Plugin could not be activated because it triggered a fatal error.

   Fatal error: Call to a member function is_enabled() on a non-object in ../httpdocs/wp-content/plugins/yet-another-related-posts-plugin/includes.php on line 68"

   - I have uninstalled and reinstalled.
   - I have attempted to install and activate version 3.2.1b4 & 3.2.2 files from forums.
   - Check box is Disqus commenting is checked.
   - I disabled Disqus, WordPress SEO and a few other plugins that were recently changed. However, error persists.

   Is anyone else seeing this, and could you please offer any advise for correction?

   Thanks in advance.

   Hmm, this seems similar to the kind of problem that we had with PHP 4 prior to 3.2.1. Have you tried version 3.2.1? Are you using PHP 4?
