I updated from WordPress 1.5 to the newest one today. All went smooth, but in relation to the calendar I get this error:
[Unknown column 'u.user_nickname' in 'field list']
SELECT p.id AS id, post_title, post_date, u.user_nickname AS author FROM wp_posts p, wp_post2cat p2c, wp_users u WHERE post_status = 'publish' AND post_date_gmt > '2006-10-01 00:00:00' AND p.id = post_id AND p.post_author = u.id AND category_id = 13 ORDER BY post_date LIMIT 6
Since I am a bit lost with mysql (what I guess, it is), can you see here something, what seems for you very wrong and what I could TRY to change?
Thanks in advance for all hints!
