ERROR IPN notification with invalid amount or currency or email

Assuming that your are using 'Paypal Standard' and/or 'PayPal Express checkout', I would suggest to log into your PayPal account and disable the IPN, because the VM PayPal plugin uses the PayPal API to handle that for you. I've been using PayPal Standard with IPN not activated for several years and despite that I receive an email from PayPal for every sucessful payment.

PayPal's IPN is not a real time service, so I wouldn't be surprised if the IPN's occationally conflict with the already sent API data exchange.

However, I'm not shure what the reason for your problem is, so other things which might be worth checking are:
Check if your vendor email and the email set in your PayPal account are identical.
PayPal doesn't send confirmations when the status is "Pending", so you might remove that from your status email settings in VM. (If you do that, check if the order emails still work - I currently have and issue with that in the latest VM version)

Check if your vendor email and the email set in your PayPal account are identical.

VM > shop > shop > tab shopper information has an adress field under 'bill to information', but I assume that is something different. And its got another emailadress then my dedicated paypal email. The paypal plugin does not have an email field. Where do I find the vendor adress?

PayPal doesn't send confirmations when the status is "Pending", so you might remove that from your status email settings in VM.

I think I got that. Is that config > tab checkout at 'Default Order Status to send email to vendor'? No pending there.

I disabled IPN. Just waiting for a sale now...

Hello

ERROR IPN notification with invalid amount or currency or email

There was a problem in paypal between primary Paypal email, and Paypal businees email in the IPN validation
I though i  had solve it
Could this be the reason : ie:
that you have 2 Paypal emails, and which  one are you using in the VM Paypal configuration ?

PayPal's IPN is not a real time service, so I wouldn't be surprised if the IPN's occationally conflict with the already sent API data exchange.

sorry, but i do not agree with you JJK
There are no conflict. The IPN is used to update the order in the VM backend.
And VM checks  some values :
- amount returned by Paypal is the same as the one sent to Paypal: this is to check that the shopper has not modified the amount just before the transaction was sent to paypal
- the merchant email returned by Paypal is the same as the one in the VM config: this is to check that it is the transaction was done on the correct paypal account
before changing the order status.
Those are security checks absolutly necessary to do before validating the IPN.
If you receive an email  with "ERROR IPN notification with invalid amount or currency or email"
then you must check your paypal account before sending the goods.

If you turn on the log option in you VM paypal configuration,a and send me the log file, then i can understand what is the problem and fix it.
Thank you
