 * Hi
    I’ve dug around the fourms but can’t find an answer.
 * I’ve recently moved a number of WP blogs from one host to a new host, and on 
   the WP2.0 installs I’m getting this error when going to post:
 * WordPress database error: [Duplicate entry ‘0’ for key 1]
    INSERT INTO wp_posts(
   post_author, post_date, post_date_gmt, post_content, post_content_filtered, post_title,
   post_excerpt, post_status, comment_status, ping_status, post_password, post_name,
   to_ping, pinged, post_modified, post_modified_gmt, post_parent, menu_order, post_mime_type)
   VALUES (‘1’,]
 * and it continues after this. Odd thing is though, it’s only the WP 2.0 blogs,
   not the WP 1.5 blogs???
 * any ideas. I’ve checked .htaccess, it’s writable and the permalinks structure
   is setup to include the date etc to avoid duplicates.

 * Check (all) the tables in MySQL. I bet the “auto_increment” setting is lost.
