Hello,
We recently upgraded to NopCommerce 3.90 and seems like PayPal Direct is no longer working. I have reconfigured the PayPal Direct, tested with the sandbox option and it was working but when I switch to the Live configuration, I get the following error message:
Payment error: PayPal error: An unknown error occurred. (UNKNOWN_ERROR)
Log:
Error while placing order. Error 1: Payment error: PayPal error: An unknown error occurred. (UNKNOWN_ERROR).
Anyone else experience this issue and have resolved it?
