I'm not sure if this is a coincidence, but on Aug 31st, I received an email from PayPal about their new buttons and logos. The 31st was the date of the last order I've received. I have not received an order since. Are customers leery of the new look that it might be fraudulent as they are used to PayPal's old look?
We updated our site with the new PayPal artwork, and saw no change in our number of PayPal orders. Our customer service hasn't received any inquiries about the change. In all, it has been well-received.
