♥kymation Posted August 14, 2014 Share Posted August 14, 2014 That's a generic error message, so it's not really helpful. Find this line in includes/modules/shipping/usps.php and uncomment it: // mail( STORE_OWNER_EMAIL_ADDRESS, STORE_OWNER, $mail_body ); Then run a test order. You'll get an email that will tell you what's being sent to and received from USPS. Post the response part here if you can't figure it out.
