The actual IPN URL is generated based on where the code for the IPN PHP file is located on your server. The old one is located right at the top level of Seamless Donations’ folder and begins with dgx-donate for legacy reasons. The new one moves payments intos its own pay folder and is the /pay/paypalstd/ipn.php thing. You should be using that unless you’re entirely unable to use SSL payments (and you better be within a few months or everything will break).
Once you have that URL, you need to go into your PayPal account and change it to the URL in question. If you’re using the sandbox mode, you need to log into PayPal’s sandbox with your sandbox account.

Thanks David,
perhaps I have not made myself clear enough. I have already set up the sandbox as you described. But paypal still tries to send to “https://herz-kinder-hilfe.de/wp-content/plugins/seamless-donations/dgx-donate-paypalstd-ipn.php” instead what I have saved as IPN in paypal…and that is where the payment notification enters in to waiting (transaction is done) .
The log shows that two different IPNs seemed to be transmitted:

An IPN is never transmitted. That’s just shown so you know the (temporarily) two choices to send PayPal to. The IPN that PayPal uses is a string you copy from the Seamless Donations settings page and paste into the PayPal settings page.
My guess is you’re not logging into the right sandbox account on PayPal, but in any case, where PayPal sends you is out of my control. It’s up to what settings you set there and what PayPal does with it.

as I mentioned David the transaction is done in terms of money transfer but waiting / retrying in the sandbox to notify with the wrong IPN:
Current settings
Notification URL https://herz-kinder-hilfe.de/wp-content/plugins/seamless-donations/pay/paypalstd/ipn.php
Message delivery Enabled
Instant Payment Notification (IPN) details
Message ID: 1ST49456NY085093N
Date/time created: 25.05.2016 14:59 PDT
Original/Resent: Original
Latest delivery attempt date/time:

Notification URL: https://herz-kinder-hilfe.de/wp-content/plugins/seamless-donations/dgx-donate-paypalstd-ipn.php
HTTP response code: 500
Delivery status: Retrying
No. of retries: 1
Transaction ID: 2CF019725G3698117
IPN type: Transaction made
It seems that neither IPN responds, so both aren’t accessible to PayPal, regardless of what’s set on the PayPal side. You’ll need to fix that first.

Hi David,
tried to find out with the support team of our provider. They interpret the error_log server side that the files that paypal wants to reach are not in the right directory. Can you help?:

I think you’ve got wordpress installed inside wordpress. Basically, it looks like you somehow installed the wordpress folder in a subdirectory of the wordpress folder. This appears to be breaking things.
