USPS shipping quote error
I'm getting shipping quote errors with eCart ever since the USPS rate change on January 26th. It only happens for heavier orders which I believe are over 13 ounces. The error is:
Error Description: DomesticRatesV4;clsRateV4.CreateSinglePostage-CreateSinglePostage;RateEngineV4.ProcessRequest - This mail service requires Ground Transportation Only.
Full Request: API=RateV4&XML=PARCEL920729594518REGULARTrue
Full Response: -2147219388DomesticRatesV4;clsRateV4.CreateSinglePostage-CreateSinglePostage;RateEngineV4.ProcessRequestThis mail service requires Ground Transportation Only.1000440
I upgraded to eCart6 thinking maybe it was something with the name changes at USPS (ie Parcel Select vs. Parcel Post) but this didn't solve the problem. Any ideas?
