Same problem on all updated to wp v3.1 sites

how you solved the problem?

royscheeren, try this

<?php
function modify_form(){
echo  '<script type="text/javascript">
      jQuery("#post").attr("enctype", "multipart/form-data");
        </script>
  ';
}
add_action('admin_footer','modify_form');
?>

if wordpress is installed in an subdirectory

in NAVT_plugin_path/js/navtadmin.js.php you can just change

define(‘ABSPATH’, $_SERVER[‘DOCUMENT_ROOT’] . ‘/’);
to
define(‘ABSPATH’, $_SERVER[‘DOCUMENT_ROOT’] . ‘/subdirectory_where_wordpress_installed/’);
