Database Error

Hi

I’m getting the following error messages coming up on my blog. Would anyone know how to fix it?

WordPress database error: [Table ‘mentor_howtoblog.wp_post2cat’ doesn’t exist]
SELECT P2C.*, POST.ID, POST.post_title, POST.post_excerpt FROM wp_posts POST, wp_post2cat P2C WHERE (P2C.category_id = ’27’) AND POST.ID != 14 AND POST.post_status = ‘publish’ AND POST.ID = P2C.post_id GROUP BY post_id ORDER BY POST.post_date DESC LIMIT 4

Thanks Jack
