SQL Syntax Error

Hi

I have this error on the jobs page on this site, It says:

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 ‘))) AND cn_wp_posts.post_type = ‘jobpost’ AND ((cn_wp_posts.post_status = ‘publ’ at line 1]
SELECT SQL_CALC_FOUND_ROWS cn_wp_posts.ID FROM cn_wp_posts WHERE 1=1 AND ((())) AND cn_wp_posts.post_type = ‘jobpost’ AND ((cn_wp_posts.post_status = ‘publish’)) ORDER BY cn_wp_posts.post_date DESC LIMIT 0, 15

I have been doing lots of research but have found it best to ask you guys as the plugin author
