Hello,

we are receiving this error message below for all new transactions since yesterday evening.
this is happening on production account (developer account works fine).
this is happening for USA authorize.net account (UK authorize.net account works fine which is using the same scripts).
we have not changed anything on the server or on the authorize.net account settings.
any suggestions?

thank you
