Hi,
I have Final price: 35, Override 30 and selected Overwrite final. In product details I can see only the final price. When I create (or enable) any tax rule I can see the final and override price.
Also there is a COM_VIRTUEMART_OVERWRITE_OFF label without value.
VM 2.0.22c
Check your price options in VM config (screen shot maybe?).
For resolving 'COM_VIRTUEMART_OVERWRITE_OFF' you need to update your language VM files. http://virtuemart.net/community/translations/virtuemart/en-GB
Probably your template overrides don't allow you to view price values. You could test your issue on standard Joomla template.
Wrong configuration. It is ok now.
Thanks :)
You're welcome.
