Jigoshop – Request a Quote not working

Just upgraded to WordPress 3.9, Genesis 2.0.1 and JigoShop 1.8.6 with the Request a Quote extension.

The Request a Quote button shows up correctly – when no price is set or no stock – but the functionality has stopped. Should be a lightbox effect with a message and email for information.

Any ideas on a fix? Is Jigoshop not fully compatible with 3.9?
