Can You please explain it a little better ? What is an "original" ? I think this prices are configurable in VM settings. Please check if this price is set to be publish. Check also tax values I remember that base price is somethimes 0 if tax was included wrong.
hi... SOLVED not in VM configuration but here: templates/gk_bikestore/html/com_virtuemart/productdetails/default.php there was some code issue in this file.
That was one of the solutions. I believe you have adjusted the code so now this small issue with tax doesnt apply . Anyway I'm happy you got it working.
