I get an error everytime I POST

WordPress database error: [Table ‘skurfboa_wrdp1.wp_post2cat’ doesn’t exist]
SELECT c.cat_name FROM wp_post2cat p2c INNER JOIN wp_categories c ON p2c.category_id = c.cat_id WHERE p2c.post_id = 124

WordPress database error: [Table ‘skurfboa_wrdp1.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

SELECT c.cat_name FROM wp_post2cat p2c INNER JOIN wp_categories c ON p2c.category_id = c.cat_id WHERE p2c.post_id = 124
Everytime I write a post, then press “save” or “publish” I get this error.
