I am trying to include the line
SHOP_CURRENCY_LOCALE = 'en_US.UTF-8'
raise ImproperlyConfigured(msg % currency_locale)
django.core.exceptions.ImproperlyConfigured: Invalid currency locale specified f
or SHOP_CURRENCY_LOCALE: 'en_US.UTF-8'. You'll need to set the locale for your s
ystem, or configure the SHOP_CURRENCY_LOCALE setting in your settings module.
The locale must be installed on your computer. On Linux or Mac you can get the installed locales by executing "locale -a".
Windows is a bit wierder and I don't think UTF-8 suffix is available. Here is a list of Windows locales. You should use the language string.
In your case that would be 'us'.
