Fatal Error

PHP Fatal error: Call to a member function setting() on a non-object in /wp-content/plugins/feedwordpress/feedwordpress.php on line 613

I’m looking at the source code, but without reading through the code for more time than I have, I don’t see the obvious problem. It’s the top line of this chunk.

if ($source->setting('munge comments feed links', 'munge_comments_feed_links', 'yes') != 'no') :
			$commentFeeds = get_post_custom_values('wfw:commentRSS');
			if (
				is_array($commentFeeds)
				and (count($commentFeeds) > 0)
				and (strlen($commentFeeds[0]) > 0)
			) :
				$replacement = $commentFeeds[0];

				// This is a foreign link; WordPress can't vouch for its not
				// having any entities that need to be &-escaped. So we'll do it
				// here.
				$replacement = esc_html($replacement);
			endif;
		endif;

I’ve disabled the plugin. The infinite error was slowing site dramatically. I would prefer this to be resolved than to find a replacement, however.

Help?
