Ok, I'm new at this forum stuff. Can you tell me what part of the code I need to change so that it works in the forums?
go back to your paypal account, create a new button. but uncheck the part that says encrypted before you create the button.
this is at paypay and has nothing to do with phpbb.
once you have that paypal code that is not encrypted, you can just paste it into a post like any other image link using bbcode.
