I've been trying to pay for deathbycaptcha using Paypal for a while now but I keep receiving the message:
Invalid response received from payment gatewayHas anyone else seen this before, and if so how to get around it? I contacted them for help. They said to try again, or contact Paypal for support. I'm not sure how Paypal can help because all my payments seem to be going through fine except this. Tried again and still same thing.
