RSVP does not register payments again

Hi,

I will have to reopen this topic due to problems I am facing on one of the websites I am working on.

Payments are going through - I can see it in PayPal and in the RSVP Sessions tab, but on redirect from PayPal to website, the message "Your attendance is awaiting payment before it is confirmed." appears and prompts the user to repay.

I tried disabling Admin Tools, friendly URLs, different types of options in RSVP config. Nothing seems to fix this error.

This appears in /administrator/components/com_rsvppro/logs/paypal_log.txt

Can you please help me with this?

The website is http://www.nzebra.ie - form here: http://www.nzebra.ie/events/register-for-nzebra-conference/icalevent.detail/2017/01/13/1/-

Adding coupon test160 will convert the prices to 0.01

Looking forward to hearing from you.
