dimensions error
I'm having the same issue.
Then I added
$Shipping_PackageArray[$Shipping_PackageIndex]["PackageLength"] = "12";
$Shipping_PackageArray[$Shipping_PackageIndex]["PackageWidth"] = "12";
$Shipping_PackageArray[$Shipping_PackageIndex]["PackageHeight"] = "12";
to confirm.php
And still having same issue. Please see error message below.
Shipping Quote Failed
