WordPress Version: 3.3.1
WP-eCommerce Version: 3.8.7.5 and 3.8.7.6.2
Mazine Theme Version: 1.5.0
Theme Author: Transparent Ideas

Update: April 2012. Due to being unable to resolve this issue ourselves or by logging a report on the Mazine support forum we have had to remove Mazine 1.5.0 from our site and are now using another theme which has been working well. Maybe this problem was specific to our setup – I don’t know, but its something to check for if you use or intend using the Mazine theme.

Visually, I actually like Mazine better than our replacement theme but while we could live with the patchy Mazine Theme SEO potentially losing a customer because of checkout issues is something we can’t have happen.

Problem:

Shipping State Disappears

When using the Mazine WordPress theme versiion 1.5.0 we’ve encoutered problems at checkout. At the second stage of the checkout process (contact details) if the customer changes their billing state then shipping state totally disappears. Both the state field name and the state value (eg. Ontario) are gone. Below is a short video capture shwoing the problem occurring on our Canadian site. My impression is that it may occur because we have taxes implemented on the site. The Mazine theme demo does not exhibit this problem and neither do several other Mazine sites I coud find but none of them appear to have taxes implemented as we have.
