USPS 5.2.1 on Os 2.3 Shipping Module Problem

[Guest]

I installed USPS 5.2.1 on OsCommerce 2.3.

 

In my Admin panel, under Modules --> Shipping, on the "Install Module" button on the right it says there are 5 options to select from. However, when I click on the button to go to the page to select the actual modules, only 4 show up (USPS does not show up).

 

I'm sure that I missed something during the multi-page instructions of file changes but I cannot figure out what went wrong.

 

HELP!

Further info:

I think there is something wrong with the admin/modules.php file because on the Modules --> Order Total section, one of the modules that I previously enabled now shows up on the "to be selected" list as uninstalled, but its button shows it as already installed.

 

Are my two problems related?

When I try to "edit" the module even though it is on the "disabled" list of modules (it does show a sort order though), I get these two errors:

 

Warning: reset() [function.reset]: Passed variable is not an array or object in /home/xxxxx/public_html/catalog/xxxxx/modules.php on line 231

 

Warning: Variable passed to each() is not an array or object in /home/xxxxx/public_html/catalog/xxxxx/modules.php on line 232

I "fixed" the problem by reverting back to my last database backup, and then installing USPS 5.2.1 *** I unknowingly had installed USPS 5.2.2 and then used the instructions for 5.2.1 ***
