Secure forms not being received – gravity forms

Hello,

When I set up a gravity form and don’t mark the page the form is on with your plugin as secure – it works fine and the notification is received.

But when I use the form on a secure page it doesn’t send the notification.

As the form works normally unsecurely, it means something to do with the secure plugin isn’t letting it be sent – Any ideas?
