Email notifications no longer sending

Hi,

I'm using Hikashop version 1.5.2 business edition on my production server. After upgrading acymailing to the lastest version my email notifications are no longer sending via hikashop.

Joomla is configured correctly, as joomla email works as well as Acymailing.

From what I can see nothing has changed on the hikashop configuration side of things. However, no emails are being sent when a product is purchased.

Can you please help?

I don't see why upgrading AcyMailing would change anything for the email sending of HikaShop. If you downgrade acymailing to the previous version, does it work again ?
What if you update HikaShop ?

Me either but it's very coincidental.

I will update hikashop and see if it changes anything.
