Hello I have a PayPal account that has Standards and also has Pro enabled on it. I can set up standard with no problem, however I am confused with the PayPal Pro plugin. The plugin ask for API username, passowrd and signature. I've followed the instructions and logged in to my account. I don't see the API username, password and signature for Pro, only Standard. Instead there is a certificate for Pro... which is not the same as the fields in the plugin. I spoke to PayPal and the guy pretty much told me that using the Standard credentials in the Pro plugin will not work. I'm sure I can't be the only person who has tried to set up pro. The reason I want to use Pro is because it doesn't set a limit for the buyer to use PayPals guest account. If PayPal Express Checkout doesn't limit the guest account I could use that but I suspect they want everyone to go Pro.
