No, it was not registered in the finance page. But the payment was received in my PayPal account.
It has worked perfectly with every other plugin that integrates with it for the past 2 years. There's nothing to configure in the PayPal plugin other than entering your PayPal merchant ID, which I have done. That is the only configuration of the PayPal plugin.I cannot reproduce this issue on my installation. But I'm willing to help you resolve the issue. Could you send me sql dump file of your ow_base_log table? I need to check if there are any error in the logs.
