We use MarketPress for our online shop and have been experiencing some issues lately with customers not being able to confirm their payment (no error is provided, it just keeps refreshing the Confirm Order page with their cart and shipping/billing info).
Also, some orders that do go through are not displaying complete information when they're transmitted to our shop. For example, the first and/or last name doesn't show up, no shipping/billing info shows up on the order, etc.
What is causing these issues, and how do I go about correcting them so we have correct orders and customers stop having to find alternate ways to place their orders??
