Not receiving payment confirmation emails (Paypal)

I am using the Paypal payment plugin and am currently testing using Paypal Sandbox.

When a user is directed to paypal to make the payment, two emails are generated:
- An email to the customer, with the title "Your order No. C4A6 is now created at www.site.co.uk/ "
- An email to the store owner, with the title "New order No. C4A6 created on www.site.co.uk/ "

However, when the customer completes the payment within Paypal, no more emails are generated. The order stays at "created" within Hikashop. I assume this is not working as intended?

Here are the possible reasons for this according to Hikashop documentation. None seem to apply in my case so I was wondering if there is any way I can investigate this further?
- Your website is on localhost (ie. not accessible from the Internet). PayPal can only send payment notifications to HikaShop if your website is accessible from the outside. No
- Your website is protected by an .htaccess which only allows the access when the correct username/password is entered. PayPal doesn't know the username/password of your .htaccess and thus cannot contact HikaShop. No
- Your website is in maintenance and only accessible for users with an administrator account. PayPal won't be able to contact HikaShop because Joomla won't authorize him.No
- The option "allow payment notifications from paypal" of the PayPal is turned off. You should turn it on. It is on
- You changed the IPs in the PayPal IPs option of the PayPal plugin. I haven't changed them. I tried clicking "refresh" but that didn't help
- You have a security component which forbids scripts to contact your website. You should ask a solution from your security component provider. Not as far as I know

Hi, thanks for the reply.

You were right. I gave up on Paypal sandbox and just tested using real transactions and it solved the problem. Sandbox has been quite buggy for the past few weeks so I guess this must be another example of that.

Thanks

I find my self in the exact same situation described!
And also I can get the CANCELLED status when I discard the payment on paypal but I can't get the CONFIRMED status when I complete the payment....
This means hikashop is able to get notification from paypal.
I've tryed any combination of checkboxes between Debug Mode and Return Methods... no changes.
....
I need to have sandbox working cause I'm also working on
onAfterOrderConfirm(&$order,&$methods,$method_id)
and I want this function to be called automatically when the order get to COMFIRMED status, so I can't pay paypal duties every time I want to test my function!!
I need Sandbox!! help help!!!

Nicolas,
I've tryed any combination of radio buttons of DEBUG MODE and RETURN METHOD in paypal plugin configuration page... nothing seems to work..
Log file is empty.
What else can I try?

Is Hikashop system working with Instant Payment Notification (IPN's) from Paypal?

Hi Nicolas,
Still can't get the notification back from Paypal...
Thinking now I'vent' listed proper sandbox paypal Ip's to get the IPN:
When I try a REFRESH I get the error I've attacched on the screenshot.
I've tryed to list it manually, found the list in here:
ppmts.custhelp.com/app/answers/detail/a_...ZC9XTGtXclVTaw%3D%3D
so I added 173.0.82.* to the list.
disabled the firewall but nothing is happening, even log is still empty... any suggestion?!
Thanks in advance

Nicolas,
I've managed to have the Log working (problem with directory permissions)
and I get this:
"

Array
(
[option] => com_hikashop
[ctrl] => checkout
[task] => notify
[notif_payment] => paypal
[tmpl] => component
[lang] => it
[language] => it-IT
[Itemid] =>
[hikashop_front_end_main] => 1
[view] => checkout
)

Could not load any order for your notification
"
I've got it from 173.0.82.126 so I think 173.0.82.* has to be added to the list.
Can you help me?
What's wrong with the notification.... Am I missing sothing? Is Itemid a refer to the order?
Tahnk you

Hi Nicolas please help I feel like left in the rain.

This is the data sent from Paypal, got from technical support:

and my server answer "HTTP Response 200Ok" so should be fine...
This is the URL they are sending the data TO:
www.skilla.com/skilla_test/index.php?opt...pl=component&lang=it

is there something missing from Paypal?!

I didn't setup any URL in my paypal account.
So I think the return URL is passed by hikashop upon the payment request, isn't it?
And the only URL I setup on the paypal plugin on hikashop is
www.sandbox.paypal.com/cgi-bin/webscr
as was suggested on this forum.
Is there a way where I can specify from hikashop the return URL?! (or the character coding standard?)
Thank you

Hi Nicolas,
I've tried your suggestion but nothing changes...
Anyway I think my server receives the notification because hikashop writes in the log file:

Array
(
[option] => com_hikashop
[ctrl] => checkout
[task] => notify
[notif_payment] => paypal
[tmpl] => component
[lang] => it
[language] => it-IT
[Itemid] =>
[hikashop_front_end_main] => 1
[view] => checkout
)

Could not load any order for your notification

But it seems like there is not enough data to understand which order has to be processed.. isn't it?!
On the IPN text from PAYPAL I posted erlier I can't see the order ID, is that right? is it missing or is it working properly?!

What else can I try?
Thank you

I can see this line on the paypal.php inside the plugin directory:

$dbOrder = $orderClass->get((int)@$vars);

it seems the invoice number in paypal is the order ID in hikashop... isn't it?
and it seems we can't retrieve it from our server side...

So paypal is sure to send it (shown on the log), paypal also receive a confirmation (a 200 response) from our server.
We can see something is written on the hikashop log as posted above
but we are unable to retrieve the order ID or the invoice variable from the data posted by paypal...

where can it be lost?!? How can I debug it?
No error in error log,
it seems a correct access in access log:

173.0.82.126 - - [20/Mar/2012:09:58:19 +0100] "POST /skilla_test/index.php?option=com_hikashop&ctrl=checkout&task=notify¬if_payment=paypal&tmpl=component&lang=it HTTP/1.0" 303 527 "-" "-"
173.0.82.126 - - [20/Mar/2012:09:58:20 +0100] "GET /skilla_test/index.php/it/?option=com_hikashop&ctrl=checkout&task=notify¬if_payment=paypal&tmpl=component&lang=it HTTP/1.0" 200 1646 "-" "-"

(our hikashop version is 1.5.4, do you think it can be the problem?)
thank you

YES!!!
Disabling the Language filter plugin it works perfectly!
How can we keep it?!
(my god this was a long way... I can finally see a way out... I hope it can help others!)
