I have the original paypal payment plugin working on the site. But I'm trying to set up Paypal pro. but I get the following error: Error 10002: Security error Security header is not valid
I set up the API on paypals side, but the Paypal pro plugin doesn't exactly match what is displayed on the site, so I'm not sure that I'm giving it the correct details. is there a general guide I can reference for getting this set up?
