Not the cleanest thing ever but here is a solution:
if (!function_exists('theme_the_password_form')) {
function theme_the_password_form( $form) {
if (isset($_COOKIE['wp-postpass_' . COOKIEHASH]) && get_permalink() == wp_get_referer()) {
$form = '<p class="error">Invalid Password. Please try again.</p>' . $form;
}
return $form;
}
}
add_filter( 'the_password_form', 'theme_the_password_form');
hopefully that helps
