USPS problem - select one method, returns another

did you uninstall and reinstall in the zc admin?

yes. it was uninstalled. new usps.php file was modified - per instructions, uploaded. reinstalled and configured.

Kadaki:

I just fixed this problem on my osc site. The problem is that the USPS just started returning the Method ID in all uppercase. The USPS module is comparing its mixed case string with the upper case string from the USPS server and then defaulting to the first method returned from USPS, which is express. Just update the module source so that 'Express' becomes 'EXPRESS', 'Priority' becomes 'PRIORITY', etc.

How do I fix this problem? Where do I go to change to uppercase?

I am having a similar problem that just started today

When Priority is checked it goes to express

could it be a problem with USPS ?

how do I fix this?

You have an out of date copy of the USPS shipping module, it was updated back in November 2007 when USPS changed the rules and did not make an announcement about this ...

This is updated in the current version of Zen Cart v1.3.8x ...

Or, for just the USPS shipping module you can get it separately and follow the instructions to REMOVE, INSTALL and reconfigure with your USER ID ... which of course you will copy and paste to NotePad BEFORE you REMOVE the old module so you have a record of it ... :smile:
