Dr Byte, so glad to have your attention on this as we started this thread some time ago and have had this happen to maybe 20 in 1600 transactions since our upgrade to zencart 1.3.0.2 We use USAepay.
My crazy post #7 should be deleted...don't know what I was talking about. Another long night.
The most recent transactions showed these possible problems:
- dots instead of dashes in phone number like 222.555.7777
- hyphen in street address like Drive-004
- Nothing odd
- seemed to be a case of rejected card.
In post #2 is the error message that one customer reported.
We repeated a transaction for another customer by phone through our connection in zencart live on his behalf and were also kicked back to step 3 with no error message. We then used the virtual termenal at usaepay to get the order done. card went through.
