First, the plug-in works fine for me (from what I see). However, looking at my server's error log I see this:
[Mon Dec 08 12:08:26 2008] [error] [client **.***.***.***] WordPress database error You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1 for query select p.id as post_id, p.post_title as title, p.post_type, p.post_date, d.*, 1 as counter, 0 as votes, 0 as voters, 0 as rating, 0 as bayesian, '' as item_trend_rating, '' as item_trend_voting, '' as permalink, '' as tense, '' as rating_stars, '' as bayesian_stars, '' as review_stars from wp_posts p, wp_gdsr_data_article d where p.id = d.post_id and p.post_status = 'publish' order by (d.user_votes + d.visitor_votes)/(d.user_voters + d.visitor_voters) desc limit 0, made by prepare_data
I'm not sure what this error means, nor do I know what causes it (sorry.) Argument could be that maybe this error isn't caused by the plug-in. So I deactivated the plug-in, and have yet to see this error again.
