Trackng down the errors with the upgrade to 1.3.8a, fresh install, database imported.
Linkpoint was randomly declining cards. After much hair pulling, it seems that when a coupon is applied, the cards are denied.
this is the error:
SGS-002301: Charge total must be the sum of subtotal, tax, value added tax, and shipping.
this only happens when coupons are used. All other charges go through just fine.
help?
