• I have just moved hosts and am getting database errors when trying to make new posts.

    WordPress database error: [Duplicate entry '0' for key 1]
    INSERT INTO migwp_postmeta (post_id,meta_key,meta_value) VALUES ('0','_encloseme','1')
    
    Warning: Cannot modify header information - headers already sent by (output started at /homepages/10/d200649402/htdocs/scraps/wp-includes/wp-db.php:121) in /homepages/10/d200649402/htdocs/scraps/wp-includes/pluggable.php on line 275

    The first part, I had a similar problem with my forum. I changed certain ID columns to auto_increment and it worked again. Do I need to a similar thing here, and which tables/olumns do I need to do it to?
