 * Thanks for the bug report. This should be fixed in SEO Ultimate 3.7.1 and newer.

 * I got a similar post:
 * `Warning: call_user_func(post_submit_meta_box) [function.call-user-func]: First
   argument is expected to be a valid callback in /home/xxxxxxxx/public_html/xxxxxxxxxx/
   wp-admin/includes/template.php on line 2868`
 * I have no idea where this. It has made the edit post/page screens go wonky. No
   ability to access any menu or even up date a page/post. Needless to say, there
   are a series of 10 slightly different errors on these pages. I am very confused.

 * Patrick,
    You can go back to an earlier version by downloading from here: [http://wordpress.org/extend/plugins/seo-ultimate/download/](http://wordpress.org/extend/plugins/seo-ultimate/download/)

 * [@patrickhealy](https://wordpress.org/support/users/patrickhealy/): SEO Ultimate
   doesn’t have a “post_submit_meta_box” function, so it sounds to me like the error
   is being caused by a different plugin. Does the error message only show up when
   SEO Ultimate is activated?
