I'm running WP 3.8 and WPEC 126.96.36.199 for a client's Website.
The have a PayPal Business account and I successfully PayPal Standard working. However, the client has asked for Express Checkout to be used instead – as most of her competitors use it.
When I activate PayPal Express Checkout (with or without PayPal Standard active as well) everything goes through as it should until I get to the "Confirm Payment" form which displayings my shipping address from PayPal. All the details are there (viewable in source code), but clicking the "Confirm Payment" button does NOT add them to the Purchase Logs. I'm ending up with orders that have no details in what so ever.
Any ideas? The same thing is happening in both production and sandboxing mode...
