Where are you getting this error, on the back end or front end?

Right under the checkboxes of posts in admin (backend).

I was having the same issue, and was able to resolve it by removing this line from the meta_box.php case for 'post_checkboxes':

$post_type_object = get_post_type_object( $post_type );
echo '</ul> ' . $desc , ' &nbsp;<span class="description"><a href="' . admin_url( 'edit.php?post_type=' . $post_type . '">Manage ' . $post_type_object->label ) . '</a></span>';

And replacing it with this, effectively removing the "Manage" link and my error went away.

echo '</ul> ';

So it may have to do with the

get_post_type_object()

function
