PayPal payment method doesn't work

Dear PKP Users
I have problem with Pay Pay payment method.
I have registered IPN in my PayPal Account but in the website it doesn’t work.
I did everything according to the manual.
When I click PayPal plugin button in the last page of the registration it links to the main webpage of the conference,
please help.

What IPN URL have you set up in your PayPal plugin configuration?
