I am very new to Paypal. I am trying to use the plugins to set up my website. Currently I have started testing my site in the Sandbox mode but I am facing the following error after completing a Paypal process:
“Validation error: PayPal IPN response from a different email address.Order status changed from processing to on-hold.”
The Paypal had already created a facilitator email for me and currently I am trying to use those details along with the supplied sandbox API credentials on my website.
I have tried to fix above error but it still appears. Can someone who had faced this issue earlier guide me in fixing above error?
