Ive just started getting the following error when customers try to pay on my site:
Error while placing order. Error 1: Payment error: LongMessage: This transaction cannot be processed. The merchant's account is not able to process transactions. ShortMessage: Invalid Configuration ErrorCode: 10548 .
It has been working fund before and I have touched the site for a while, paypal is all set up and the api settings are correct on the site.
I'm running V3.8, any ideas?
