[Plugin: Add Multiple Users for WordPress] Hook user_register and AMU

Hello,

I made a hook to create new posts for each new registered user.
This works fine when I add a user with WordPress.
But when I add multiple users with AMU, the user are created but not posts.
you have an idea?

Here is the beginning of my hook.

Thank !

global $wpdb;

}
add_action( ‘user_register’, ‘create_new_user_posts’);?>
