One-Page Checkout [Support Thread]

[lat9]

I've just submitted v2.1.3 of OPC to the plugin moderators for review; I'll post back once it's available for download from Zen Cart. You can also download directly from the plugin's GitHub repository: https://github.com/lat9/one_page_che...ses/tag/v2.1.3

This release contains changes associated with the following GitHub issues:

#204: Add information sidebox link for the order_status page.
#206: Correct session-handling when javascript is disabled in the customer's browser.
#207: Remove unwanted guest-account address-book entries.

Note: At a minimum, I highly suggest that stores running any previous version of OPC that included the guest-checkout feature update their copy of /includes/functions/extra_functions/one_page_checkout_functions.php to use the v2.1.3 version:
