Paypal - Refused Invalid Response after update

-- HikaShop version -- : 2.6.2
-- Joomla version -- : 3.4.8
-- PHP version -- : 5.4.45
-- Browser(s) name and version -- : Chrome 49.0.2623.110

We've just updated to Hikashop 2.6.2 from 2.5.9 in the process it seems to of broken our PayPal Payment Plugin. Now when a payment is made we get an email saying "A paypal notification was refused because the response from the paypal server was invalid". What do I need to check or change to correct this as we're still receiving payments but it's not updating on the order from created to confirmed.

Thanks
Jamie

Hello,

We have the same in our webshop too.
Please see the screenshot with the given message.

I had PayPal redo sending the payment verification twice, same message from our Hikashop.

Hope this can be solved soon, as we will now have to have people verifying the incoming orders from PayPal manually.

All the best,

Hello,

We just fixed it on our end, you'll have to download the last Hikashop version through our website, install it and test it again.

Thanks for your feedbacks.

Hi, I am also having this issue! I have just updated your latest version and when you press the 'pay now' button nothing happens?? I now cannot take any order because of this?

Updating seems to have taken out the 'paypal URL' from the plugin?? can you advise what should be in there please?

As stated in the documentation here Paypal Plugin Documentation you can see if your site is like you should use

Hello,

I am having the same problem on a customer's site. which started with the update to 2.6.2.

In addition to that issue, it seems that some of the "created" orders do not appear in paypal's transaction log, at all.

So, there seem to be at least two problems. One with the IPN notifications and one somewhere in the initial paypal call.

I have already reapplied a newer 2.6.2 update and still having issues with paypal checkout not working half of the time.

I have now applied the patch where we set:

$verified = true;

$verified = preg_match('#VERIFIED#i', $response);

So, some (or most?) of the issues might not be Hikashop's fault at all...

Have a look at this link and also the comments below the graph.

It seems that some of our problems are aligned with major paypal issues.

Hello Nicolas,

Yes, you are right on that I stated in my last post that some or most of the paypal checkout problems are originating from Paypal itself.
It was just bad timing, which resulted in people thinking, there was still something wrong with hikashop.

Unbelievable though, that paypal has such big problems and cannot find solutions for days now. They also had some minor issues during the past months.... Unbelievable...
