Error post.php after publishing or updating posts in WP 3.7

Hi guys,

I’ve updated my blog to WP 3.7 but I get a suck error everytime after publishing or updating my posts.

This error display each time I press Publish a new post or Update any posts:

WP_Post Object
(
    [ID] => 5807
    [post_author] => 1
    [post_date] => 2013-10-26 07:19:00
    [post_date_gmt] => 2013-10-26 00:19:00
    [post_content] => Testing content...
    [post_title] => Test new post
    [post_excerpt] =>
    [post_status] => publish
    [comment_status] => open
    [ping_status] => open
    [post_password] =>
    [post_name] => test-new-post
    [to_ping] =>

    [post_modified_gmt] => 2013-10-26 02:25:03
    [post_content_filtered] =>
    [post_parent] => 0
    [guid] => http://mydomain.com/?p=5807
    [menu_order] => 0
    [post_type] => post
    [post_mime_type] =>
    [comment_count] => 0
    [filter] => raw
    [format_content] =>
)

Everything is okay except this error. I’ve tried to deactived all plugins one-by-one but this error still remains.

Any solutions for this error? Thanks so much!
