PHP Notice: Undefined index

  • Hey,
    thanks for this plugin.
    but it generates quite a lot of php notices:
    Undefined index: 00 in /…/wp-includes/locale.php on line 271

    this is due to your hacky approach to make the year filtering possible and maybe there’s no other way then.

    i suppose the only way to get rid of this would be to use a separate filter formfield here…

    thanks again
