Hello, there are a number of other posts like this one, but none that I could find with exactly the same symptoms. I moved hosting package for my blog. You can see the site at http://www.kouya.net.
Since moving, I have multiple database errors occuring, all with similar wording:
The categories section in the sidebar now says:
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 try to manage posts I get the following in the comments field:
WordPress database error: [Unknown column 'comment_count' in 'field list']
SELECT comment_count FROM wp_posts WHERE ID = '36'
And on attempting to write a post, the upload section reads:
WordPress database error: [Unknown column 'post_mime_type' in 'field list']
SELECT ID, post_date, post_title, post_mime_type, guid FROM wp_posts WHERE post_status = 'attachment' AND post_parent = '-1136282218' ORDER BY post_date_gmt DESC LIMIT 0, 10
