USPS Module Help Please! in Shipping Modules Posted November 21, 2007 In the admin of the USPS shipping module, all of my shipping type selections turn to "array" and my checkout will still not allow the use of USPS module. Is it possible that the upgrade.sql did something to the database? I even used files from an already repaired store and replaced the ones I got from the new updated usps module. Really need help badly.
