I'm using a fairly new Magento 22.214.171.124 installation, with no changes to the core. When trying to make a tax rate at 0%, Magento returns the following error upon save: Rate Percent should be a positive number.
I'm recreating a Magento webshop, based on a Magento 126.96.36.199 installation, in which the exact same values have been set.
Is this just a bug in Magento 1.8, keeping me from setting a tax rate with 0% tax, or am I missing something?
Any help would be appreciated.
