 * Using the latest FWP 20130504, I notice in my error log file the following:
 * [04-May-2013 10:17:02] 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 SQL_CALC_FOUND_ROWS wp_rb_posts.
   ID FROM wp_rb_posts INNER JOIN wp_rb_term_relationships ON (wp_rb_posts.ID = 
   wp_rb_term_relationships.object_id) WHERE 1=1 AND ( wp_rb_term_relationships.
   term_taxonomy_id = 6861 made by require(‘wp-blog-header.php’), wp, WP->main, 
   WP->query_posts, WP_Query->query, WP_Query->get_posts
 * I have no idea what is causing this error, but I see I have it in several blogs
   using FWP, but not in blogs not using it.
 * How can I best debug the problem? (google searching didn’t help me much)
 * Thanks.

 * Update: I found out that this is caused by turning on “Optimize IN clauses”
    
   I turned it off, and stopped getting the errors.
 * Please fix this option.
 * Thanks.
