Multiple confirmation e-mails are being send to customer

-- url of the page with the problem -- : www.tweedehandjes.com
-- HikaShop version -- : 3.3.9

Hi,

After the customer placed an order, he gets multiple confirmation emails.
Could be 2 or 8... Do you know if there is a bug?

Please let me know if and what information do you need else.

Kind regards,
Joyce

Hello Joyce,

Firstly can you download the last Hikashop version through our website, install it and test it again ? Thank you.
