i've just upgraded my wp to 2.0 and now it has 2 problems:
1st, on the front page, the Categories section on sidenav shows like:
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_ID asc
2nd, I tried to login to the admin site but all the pages under http://mysite/blog/wp-admin/ is reported as:
You do not have sufficient permissions to access this page.
I'm not sure if someone else asked similiar questions before, but it will be great appreciated if anyone can help me on these, thanks.
