Thank you for the reply.
I upgraded to the latest HikaShop Business version and enabled user download space but now I receive an error message: "No shipping method found."
These are zero weight, zero dimension virtual products delivered only by download. Other than enabling the user download space I have changed nothing. This message did not appear in the previous version of HikaShop Business.
Also, and this did not happen with the previous version of HikaShop Business either, I now see "Card validation code" directions being displayed over the search bar area of the page. No doubt this is a conflict with the responsive JoomlaBamboo template that is in use. So, how do I fix this? Is there a new HikaShop configuration setting someplace to control this?
Thanks.
