We have posted an update to the shipping rates module that addresses a few minor issues. Specifically, FedEx International overnight and USPS First Class not displaying correctly on specific Apache installs.
This is not a required upgrade but it is recommended since it will enhance the customer checkout experience.
To upgrade your PHP cart install, please download the zipfile using the URL below and the upload the file located in the /sitestorepro/checkout/shipping/ folder up to the same folder (/sitestorepro/checkout/shipping/) on your hosting account.
All future version of Site Store Pro will include this patch and we have already patched the current download (install) zip file(s) in your account manager as well.
