WordPress Database Error

Hello Everyone,

This is my first wordpress blog and I am following instrucitons in a book on how to do this. When I went to write a test post, I got a wordpress database error. The post was posted on my blog, however.

Also, I got the header error when using another theme every time I went to activate a plug in..so changing the theme fixed that. Anyhow, here is the error:

WordPress database error: [Table ‘markd_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 = 7

WordPress database error: [Table ‘markd_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

WordPress database error: [Table ‘markd_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 = 7

WordPress database error: [Table ‘markd_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 = 7

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

Any help would be aprreciated
