USPS Module Help Please! in Shipping Modules Posted November 20, 2007 Did you delete your old usps.php or just rename it. You HAVE to delete the old one before you install a new one. I think this is why it is trying to redeclare class usps.php since two files are trying to declare it. I initially didn't read the instructions and uploaded the new one OVERWRITING the old one. Then, when that didn't work, I read the instructions (doh!), deleted the current one and uploaded the new one with no luck still.... Any ideas of how to fix it?
