WordPress database error – can’t add categories

Hello,

I updated to 2.2 and I’m using the Redoable 1.2 theme. When updating I downloaded the files from WordPress, then uploaded them to the FTP site and set write-over to ‘all’.

I imported an OPML file for a list of links from Firefox which did work at my blog at WordPress.com, and while it did import them, each one came with this error message (the link count goes up with each one):

WordPress database error: [Unknown column ‘link_count’ in ‘field list’]
UPDATE wp_categories SET link_count = ’85’ WHERE cat_ID = ‘1’

When I try to add new categories, it won’t do it and I get this:

WordPress database error: [Unknown column ‘links_private’ in ‘field list’]
INSERT INTO wp_categories (cat_ID, cat_name, category_nicename, category_description, category_parent, links_private, posts_private) VALUES (‘0’, ‘tradtional media’, ‘tradtional-media’, ”, ‘0’, ‘0’, ‘0’)

When I add the ‘Links’ widget, it doesn’t show anything except this error message in the sidebar:

WordPress database error: [Unknown column ‘link_count’ in ‘where clause’]
SELECT * FROM wp_categories WHERE cat_ID > 0 AND link_count > 0 ORDER BY cat_name ASC

How can I fix this?

Thanks,
