Errors with WordPress 3.6

Hi,
I think it’s a problem unrelated to thw WP version, but it depends on some changes on PHP 5.4
Thanks for reporting, I’ll fix it soon.

Thanks lopo,

When can we expect an update?

You can temporarily remove the warnings by changing line 31 of the file, duplicate-post-common.php to:

if ( !$post = get_post( $id ) )

Thanks David.
