USPS Shipping Module does not show up under Modules/Shipping

[Sergeh]

You need the code file in:
/includes/modules/shipping/usps.php

Check the download again and reload the files to the server in the correct directory ...

I came across this thread and I am having the same issues. I have uploaded the most recent version of the USPS module but it does not show up in the Module -> Shipping section of the admin area. There is an empty space where it should be, but I can not do anything. See screenshot: http://screencast.com/t/0NruU3sc

I have tried clicking on the empty line and clicking install but nothing happens.

I checked the actual files that are uploaded and they are correct - language file in the appropriate language folder, and code file in the appropriate module folder.

I checked through Tools -> Developers Tool Kit and searched the two usps.php files and they show up correctly:

/var/www/html/store/includes/languages/english/modules/shipping/usps.php
Line #14 : * @version $Id: usps.php 2015-05-31 ajeh Version K7 $

/var/www/html/store/includes/modules/shipping/usps.php
Line #15 : * @version $Id: usps.php 2015-05-31 ajeh Version K7 $

Any help would be appreciated.

Sure...

Zen Cart v1.3.9h/v1.3.9h
Not upgraded
Problem with USPS module
PHP Version: 4.4.7 (Zend: 1.3.0)
Database: MySQL 5.0.67
I'm assuming it's been like this since USPS stopped supporting V3 api

Let me know if you need any of the other items

Based on the old, out dated and no longer supported version of php (this is a *hint*), you need to edit the file:
/includes/modules/shipping/usps.php

and follow the instructions on this line, approximately line 86, in the code:

  function __construct() { // for older php < 5.1.0 change to usps() instead of __construct()

NOTE: you should also then upgrade your Zen Cart version to at least the newest one, but not until you get you php updated ...

I changed it to function usps() and now the empty line is gone, and i am not able to edit any of the other modules..see screenshot: http://screencast.com/t/5NTXynsoHe

Sound like you have a backup file in the directory:
/includes/modules/shipping

in which case you most likely now have a debug log in you /logs (/cache in old out dated versions of Zen Cart, again a *hint* here) ...

[Sergeh]

How do I get rid of it? I don't see a /cache folder

[Ajeh]

How do you get rid of what?

As to no /cache that is really needed in v1.3.9, as well as a good idea for other versions, as that is where the debug logs go in v1.3.9 ...

[Ajeh]

What do you have set in:
/includes/configure.php

for the line that contains, at the end of the file:

define('DIR_FS_SQL_CACHE'

[Sergeh]

ok i found the cache folder.. here is the error message:
