I just upgraded the USPS plugin from the March 27 version to the July 28 version, but now I get the error:
Missing Keys or Out of date you should reinstall!
In next to this in the shipping selections. I also see on the right hand side that the only option is still the March 27 version.
I installed just two files /languages/english/modules/shipping/usps.php and modules/shipping/usps.php
Did I miss something?
