I upgraded to version 2.1.1 last week. Since then customers cannot see the option to use USPS First Class as a mail option.
When I go to the Admin and look at the settings it looks like nothing has changed. When I try and test the First Class I get a message: Invalid First Class Mail Type.
I deleted the shipping type and recreated it. Still having the same problem.
Here is the log when I try and test it. Any ideas would be extremely helpful.
