I am working with trial version of dolphin. I have installed the payment and membership modules, then I have created a new payed membership level, then I have followed the steps listed in http://www.boonex.com/n/2checkout_in_dolphin to enable 2chechout payment, but when I created a new payment for an new test user to upgrade form standard to this featured membership and after the payment I have received this message "Check key is incorrect" on the payment result page. Was that a bug. actually this matter will effect my purchasing decision.
Thanks.
