I am using the usps shipping module. Cart version is 1.3.8. Had huge issues a couple of weeks ago but they were resolved and the module was working fine up thru last night.
This morning, the cart is getting stuck during checkout on the shipping page, which displays an error message saying we do not have a shipping method for the customers address. Same error as before.
However, when running in the debug mode, I receive an email which is totally blank. Last time I got an email saying I did not have access to the usps server, this time, no message at all.
Have uninstalled and reinstalled twice, and talked to the post office twice, and they again say it is a zen cart issue.. Without a debug message, I am not sure that it IS on their end.....
Any suggestions?
Many thanks in advance,
