Strange “Sidebar” problem

Hi there.

On my wordpress sidebar, underneath the “Archives” and “Links” sections, I have this horrible error underneath

“WordPress database error: [Table ‘blog.wp_posts’ doesn’t exist]
SELECT DISTINCT YEAR(post_date) AS year, MONTH(post_date) AS month, count(ID) as posts FROM wp_posts WHERE post_date < ‘2005-07-14 19:50:00’ AND post_status = ‘publish’ GROUP BY YEAR(post_date), MONTH(post_date) ORDER BY post_date DESC”

Now this is wierd. because my WP database is called “wordpress” and I have a separate DB called “blog”.

My wp-config.php seems to have the correct settings, yet the sidebar seems to be looking elsewhere!

This has only happened recently.

Any ideas?
