I'm using WP, 3.5.1, multisite with Domain mapping Plugin, with your last version of Paypal add on. I have some problems:
1 - in the WP back office I can't see Gravity Form add on (I downloaded them through your site)
2 - I'm using pay pal donation: is it possibile to pass through the form some hidden value like: ID donation.
3 - I created a donation botton with paypal backoffice. Is it possible to pass through the form the hosted_button_id value (the button code I have created)?
4 - I can't use paypal with Transaction Type for Product and Services to obtain a Donation form. I have a form made of these fields: Name, Email, Product (the price is defined by the user). I see paypal page, I can fill in the fields, but I can't finish my payment process. The system always returns me this errore: you must choose a payment method.
5 - Can I set an automatic redirect to my site, just after the end of the payment?
