Error when Posting posts or pages

Hey there, whenever I post a new post or page I am getting this error:

WordPress database error: [Table ‘saaffil_wrdp2.wp_post2cat’ doesn’t exist]
SELECT cat_ID AS ID, MAX(post_modified) AS last_mod FROM wp_posts p LEFT JOIN wp_post2cat pc ON p.ID = pc.post_id LEFT JOIN wp_categories c ON pc.category_id = c.cat_ID WHERE post_status = ‘publish’ GROUP BY cat_ID

WordPress database error: [Table ‘saaffil_wrdp2.wp_post2cat’ doesn’t exist]
SELECT cat_ID AS ID, MAX(post_modified) AS last_mod FROM wp_posts p LEFT JOIN wp_post2cat pc ON p.ID = pc.post_id LEFT JOIN wp_categories c ON pc.category_id = c.cat_ID WHERE post_status = ‘publish’ GROUP BY cat_ID

Warning: Cannot modify header information – headers already sent by (output started at /home/saaffil/public_html/wp-includes/wp-db.php:160) in /home/saaffil/public_html/wp-includes/pluggable.php on line 391

The post and page still goes through but I would like to resolve this if possible.

regards,
