Re posting this question 3rd time..
I have successfully received an order and now want to create shipping label for USPS.. but the on clicking on Create Shipping Label, the Package that appears shows some disabled fields.e.g. the dimensions and the type. Because of which I cannot create shipping labels.. as it generates error..
Insufficient information to create shipping label(s). Please verify your Store Information and Shipping Settings.
