Unknown column ‘category_nicename’…
Just installed WordPress on one of my TextDrive accounts and am getting the following error at the bottom of the page when I click on one of the category links. The error changes to ‘category_id’ if I don’t include a SEF URL setting. I looked at the wp_posts table and indeed both category columns are missing.
Couldn’t find a way to deactivare PHP error messages in the admin. Here’s the error:
Database error: [Unknown column ‘category_nicename’ in ‘where clause’]
SELECT COUNT(ID) FROM wp_posts WHERE 1=1 AND (category_nicename = ‘ramblin’) AND post_date_gmt <= ‘2004-10-21 07:37:59’ AND (post_status = “publish”)
