In the topic https://forum.virtuemart.net/index.php?topic=149454.msg533635#msg533635 (https://forum.virtuemart.net/index.php?topic=149454.msg533635#msg533635), I wrote that in the new vmadmin template, when editing a product, its image disappears.
So I switched to the old one. But here, too, a bug awaited me.
The Child product price, specified in the Product Parent, disappears on the site when opening and saving the Child product.
But it is present in the admin panel. If you then open and save the Product Parent, the price on the site is restored.
