Multiple Confirmation Emails

Hello,
I am in the process of creating my first e-commerce website using HikaShop. I did a test sale yesterday in order to experience the entire purchasing process. Everything went smoothly but then I (as the customer) received 13 confirmation emails. In the admin area under the Order History it shows "automatic payment notification received" 13 times. I am using the PayPal payment method. Is this an issue with HikaShop or PayPal or something else entirely?
Thanks!

It means that there was an error on the notification page triggered by paypal on your website and thus paypal thought that it didn't work. Thus, it sent the message again and again until it stopped for good.
It's impossible to say what is the problem without looking at the notification page on your website. Could you give a link ?

I have attached screenshots of the Order Page, not sure if this is what you were referring to as the notification page. If not- where is that?
Thanks for getting back to me. Here is the top part of the screen:

Here is the bottom part of the screen:

No, what I need is the URL of your shop so that I can order something and see what paypal is seeing for that order.

Here is the url: lylatov.com/shop
If you actually need to purchase something there is a "test monster" which is $.01 and a "test" free shipping option.
I appreciate any help I can get, the site is ready to go except for this one issue.
Thanks!

The notification page is working ok up until the IP check which fails since we're not paypal.
We would need an FTP access in order to put traces in the code and try to understand the problem.

Can I give you the FTP info in a way that is not public?
Thanks.

Sure. You can use our contact form: www.hikashop.com/en/support/contact-us.html

I have just sent an email containing FTP info using the link you provided.

Thank you. We'll look at that today.

I couldn't find the problem as there is no error message as all. Everything seems to work fine during the notification process so I don't know why paypal tries to resend the notification several times.

In order to circumvent the problem on your website, I've added the code:
if(in_array($dbOrder->order_status,array('confirmed','shipped'))) return true;

after the code:
if(empty($dbOrder)){
echo "Could not load any order for your notification ".@$vars;
return false;
}

in the file plugins/hikashoppayment/paypal/paypal.php

That will avoid that the process is done several times but I'm afraid that you will have to reapply that modification when you update hikashop in the future...
