PayPal and FuturePay don't work. Customer remains on the Checkout. Jigoshop cart

After activating this plugin our checkout method doesn’t work. Please help, since our customers can’t place any orders via PayPal and Future Pay. We use Jigoshop shopping cart.

When a customer clicks “Place Order” with PayPal or FuturePay, Checkout page refreshes and nothing happens.

Thank you in advance!
