I've just had to reload my databases from a backup and now I'm having trouble displaying my categories (and comments, too by the way). Instead of the categories list in the sidebar I'm getting the following:
WordPress database error: [Unknown column 'category_count' in 'field list']
SELECT cat_ID, cat_name, category_nicename, category_description, category_parent, category_count FROM wp_categories WHERE cat_ID > 0 ORDER BY cat_name asc
* No categories
When I go to the category list in the admin area they are all there and the posts all have categories listed. Any ideas?
