Every once in a while I receive notifications from customers stating that when they attempt to order an item on my website they receive the following error: I got an error message saying that my payment could not be
processed because of an error message saying" Sorry, your payment
request can not be processed at this time for the following reason:
The value for the variable publisher-name or merchant being submitted,
, is incorrect. Check setup email for proper value."
Can anyone tell me why this is happening and why it only happens to some people and not others?
