I always get 2 security warnings in Firefox when I press the last "Continue" Button in Paypal to finish the transaction before you get back to the Treasury return page.
It's something that Treasury tries to get data from the secure area.
Thank you very much for the answer,
Would there be a possibility to include the member names in the PayPal Receipts I receive. Then I could put in the details manually in the case the people would follow the security advice.
