Hi Lion,

The error message(IPN handler did not return array) is for developers only and have no significance for users, so you can remove it. Open web/sim/include/CCheckoutSimulator.inc.php and comment Line 110 out to suppress the error message.

(example)

//$sim_ret[_ERR_KEY_] = "IPN handler did not return array: " . $ipn_ret;
