Problem Posting after restore

I just moved to a new host. I restored my data, but now I’m not able to post. Here’s the error I’m seeing when I try to post.


WordPress database error: [Duplicate entry '0' for key 1]
INSERT INTO wp_postmeta (post_id,meta_key,meta_value) VALUES ('0','_encloseme','1')

Warning: Cannot modify header information - headers already sent by (output started at /home/[DELETED BY ME]/public_html/wp-includes/wp-db.php:102) in /home/[DELETED BY ME]/public_html/wp-admin/post.php on line 60
