stopped receiving order email

-- url of the page with the problem -- : www.hopgarland.com
-- HikaShop version -- : 2.3.3
-- Joomla version -- : 3.3.6
-- PHP version -- : 5.3.14

I just heard from someone I set a shopping cart for up for that they have stopped receiving order-related email from Hikashop. They get email from PayPal when the order has been paid for but nothing from the Hikashop package. This was working fine and just stopped. I have made sure that they've checked their spam folder but the emails aren't being flagged as spam. I had not made any changes to the site when it happened and neither had they., I have checked the email settings in the Hikashop configuration and they appear fine. Can you hazard a guess as to why emails might have stopped being sent?

Hello Roman,
Reading that thread will probably help you :

HikaShop uses the standard joomla email sending functions. If you have a problem only on that email, it means that the problem is the content of the email.
Fist, you should check your different settings in the hikashop configuration under the tab mail. The encoding might not be correct for your email server, it could the ad name option , etc.
What you could try also is to send an email via the interface in sales when changing an order information. Does that work ? If yes, then, the problem is really the content of the order creation notification.
It could also be that your hosting company doesn't allow you to send more than one email per thread and at the end of the checkout, two emails are sent (1 to the customer and 1 to the vendor). So you might want to check on that with your hosting company.
