Also,
FS contact form plugin has the same issue, and here is how to fix it:
function my_action_url_ssl($form_action_url, $form_id_num) {
// control which forms you want this on
$all_forms = true; // set to true for process on all forms, or false to use settings below
// force form action URL to be SSL
$form_action_url = preg_replace( ‘|https://|’, ‘https://’, $form_action_url );
return $form_action_url;
}
//filter hook for form action URL
add_filter(‘si_contact_form_action_url’, ‘my_action_url_ssl’, 1, 2);
I put it here cause this may help you.
Thanks,
