Ok, looks like the SEF URLs were messing with it. However, the website doesn't seem to be receiving the payment notifications. I've tried setting the PayPal verify URL to both www.paypal.com & www.paypal.com with neither working.

The current PayPal IPN settings are still set to my old website:
www.myoldwebsite.com /administrator/components/com_virtuemart/notify.php
Do I need to change it to something else?

PayPal sends this notification URL with purchases made in my new website though:
www.mynewwebsite.com/index.php ?option=com_vmeticket &task=paypal.receivePayment&order_id=9

Dear,

It's hard to say where should be the problem. We'll check it. Could you send me link to your page and FTP access to Tato emailová adresa je chráněna před spamboty, abyste ji viděli, povolte JavaScript
