I got an email today from a local developer who was asking me some questions about the recent WooCommerce 2.1 update. When she updated she got an error related to her shipping methods. With a quick search she was able to discover our recently created WooCommerce 2.1 Issues page which mentions a fix for that error:
…You can delete that specific file from your theme until this issue has been patched by your theme developer for a temporary fix.
The problem is that in this case she's the developer. She created a custom theme for her client and she has to figure out exactly which template has changed and how to change it back. The question is how? What is a more permanent fix?
