Thanks Jumbo! We'll give that a try. Kind of amazing that we have to hack 3 core files to get the software to work, but I suppose that is "Brand Virtuemart". And now it will be un-updatable, or do you think this fix will be in the next release?

I believe my guess is as good as yours.

that was fixed in my local core one day later afte report and of course fixed in vm4.2.14, which was released a week after the release of vm4.2.12.

So members had this problem just a week and most members did not notice it, actually

I have the same problem now, on 4.3.4  It happens on some product pages, but not all, and only on child products. If I delete the child product and create a new one, the customers can order the child product a couple of times, then the error comes back, and I have to delete/create again. Is there a permanent fix that will work even after a new update?

Sorry, my mistake. That was the Joomla version. My Virtuemart version is 4.2.12. I will wait for the 4.2.14 to get available
