For any of our Miva clients that use Stone Edge Order Manger, please make sure to update your order import module.
In 9.8 Miva changed the name of the payment method code for PayPal Express Checkout. It used to be PAYP and it got changed to PPAL_OSEL. The Stone Edge import module had a hard coded conditional looking for PAYP method code so when they changed it, it broke things. Miva worked with Stone Edge to update the module.
Feel free to reach out to us for an updated version of the Stone Edge import module.
