Website not sending New Order notification when using MercadoPago

This thread is a unified conversation coming from here:
http://wordpress.org/support/topic/order-status-doesnt-change-to-processing-even-though-the-payment-is-correct?replies=13
and here:
https://github.com/woothemes/woocommerce/issues/4784

I have two WP websites using last versions of WordPress, WooCommerce, and this plugin for MercadoPago.

One site is using mod_security and CloudFlare
The other site IS NOT USING mod_security nor CloudFlare.
Although, even if both sites are hosted in different servers, they have the same behaviour:

If a customer make a purchase selecting BACS, the site send the New Order notification email to the site owner and to the customer, and sets the operation as “on-hold”. Everything ok.

But if a customer make a purchase selecting MercadoPago, and no matter if the customer selects credit card or the other payments available via MercadoPago, the site send the New Order notification email ONLY to the customer, and sets the operation as “on-hold”, EVEN IF the customer completes the payment using credit card in MercadoPago. The site owner will receive a notification by mercadopago.com, not the website, only if the payment is completed. In the meanwhile, site owners are totally unaware of any operation purchase taking place in the site. And obviously, people cannot be constantly refreshing the Orders screen in WooCommerce to see when a new order is placed.

Mail notifications should be sent as with other payment options when are set as on-hold. I guess this weird behaviour is not the intended one. Is this statement correct?

Please note:
– I deactivated firewall and mod_security on purpose in one site. And the other is not using that at all.
– This rare behaviour is happenning even if I use MercadoPago in sandbox mode.
– I enable the log and on every operation one can clearly read:
```
05-20-2014 @ 13:52:50 - Getting client credentials...
05-20-2014 @ 13:52:50 - Received valid response from MercadoPago
05-20-2014 @ 13:52:51 - Payment link generated with success from MercadoPago
```
May the above be considered as a correct IPN response?

Now, my first question (just to clarify): what component is responsible for sending the New Order notification email to the site owner? WooCommerce? or the used plugin itself?

I just want to solve this issue.
So, help please 🙂

This excerpt from the log does not show the MercadoPago IPN data.
This saying only that MercadoPago consulted on and managed to generate the payment link, in this case the client will use to make the payment on MercadoPago.

No payment method sends emails about new orders, much less the BACS.

Emails are sent automatically by WooCommerce when the order was the status changed from pending to on-hold or processing.

If you do not receive any email, their status are not being changed… This means that you server are not receiving the MercadoPago IPN post!

What link you used to set up notifications in https://www.mercadopago.com/mla/herramientas/notificaciones ?

ok, Claudio. May it comes to the way PHP is compiled? One server is using PHP 5.2.17 + Apache 2.2, and the other one is using PHP 5.4.20 + Apache 2.4.
Both them have the following PHP functions disabled by security reasons:
popen, proc_open, shell_exec, passthru, exec

May this effect any function/feature/request in the MercadoPago API?

Nop.
Can be blocked by mod_security, firewall, .htaccess and other settings on the server to block external POSTs.
You may even be using plugins that are blocking it.

But you did not answer my question:

Notifications are sent to http://domain.com.ar/?wc-api=WC_MercadoPago_Gateway

I havent noticed before that MercadoPago have a Test button for the IPN. I tried it and they say:

{"protocolVersion":{"major":1,"minor":1,"protocol":"HTTP"}, "reasonPhrase":"Not Implemented","statusCode":501}

The same happens with both websites. I have two different MercadoPago accounts. Both are resulting in the same error message.

Any ideas?

This is wrong, this need to returns 500, we use: https://codex.wordpress.org/Function_Reference/wp_die

Well, I found the MercadoPago IP was in a blacklist in the firewall, from a moment in which mod_security was still enabled and captured and blocked the IP. Now I whitelisted the entire IP range belonging to mercadolibre.com.ar and now the Test returns an ok:
```
{"protocolVersion":{"major":1,"minor":1,"protocol":"HTTP"}, "reasonPhrase":"OK","statusCode":200}
```
Now the notifications are being correctly sent.
Thank you very much for helping me in thinking a solution 🙂

Thanks for:

Curiously, your PagSeguro plugin is also made by Claudio Sanches: http://wordpress.org/plugins/woocommerce-pagseguro/

Maybe this guy is unaware of any change in the woocommerce api?

Hi, i have a very simple cuestion.

Can I use this plugin and let the users make the payment in Venezuelan Bolivares?

I know this cuestion is off topic but… The life is too short to creat a new thread for that.
