USPS SHipping module error

[dldesigntore]

I did something wrong when installing the USPS shipping module update and now get the error:
"
Fatal error: Cannot redeclare class usps in D:\Hosting\5853833\html\includes\modules\shipping\usps.php on line 798 "

When I try to access the shipping module.

Also, does anyone know what file the information for the USPS shipping is saved in? I am trying to find my old (worked) USPS ID from an otherwise trashed (failed) ZenCart installation.

It actually sounds like you have a backup copy of the usps.php shipping module loaded on the server ...

The /includes/modules/shipping is an autoloading directory ...

NOTE: this can also happen if you accidentally overwrite the language file with the code file in:
/includes/languages/english/modules/shipping

Thanks, Ajeh, that fixed the first problem. Any idea on the second issue (in what file the information on id and such for the USPS shipping is stored)?

What does this mean, exactly? I've noticed that some modules seem to be scanned by ZC when they're installed, which is a new one on me, as I'm accustomed to php files being interpreted on the fly. Is this what you're talking about?

You can try contacting USPS if you cannot find your original email ...

You might try checking USPS site and see if they have something to resend you the information based on your email address ...

There are several directories in Zen Cart that are auto loading, meaning that any file in them are "loaded" ...

So if I have a file called:
/includes/modules/shipping/usps.php

and another file called:
/includes/modules/shipping/usps-old.php

it would load both files ...

The problem is, both files contain the same code and causes the error as the file content can only be loaded once ...

I rename files to:
/includes/modules/shipping/usps.php_OLD

so that it is not a php file ...

NOTE: The better solution is to not leave backup files on the server ...
