 * I just upgraded from 2.0.1 to 2.1.3 and got this error after I ran the upgrade
   script:
 * `WordPress database error: [Duplicate entry '0' for key 1]
    INSERT INTO wp_categories(
   cat_ID, cat_name, category_nicename, category_description, category_parent, links_private,
   posts_private) VALUES ('0', 'Upcoming Interviews', 'upcoming-interviews', '','
   0', '0', '0')
 * Is this something I need to be worried about? If so, what should I do? I did 
   backup the old files but would hate to have to re-upload them again if avoiding
   it is at all possible.

 * Based on this thread: [http://wordpress.org/support/topic/72981?replies=11](http://wordpress.org/support/topic/72981?replies=11)
 * Wonder if the wp_categories doesn’t have the auto_increment set for the cat_ID
   field?
