Virtuemart 2.0.18a.
After submitting product notify form user is suppose to be redirected to product details page. And he is but in path one parameter is omitted: product category id. And thus link is wrong and looks like that:
component/virtuemart/a-m-s-g-the-principle-of-evil-becomes-the-ideal-of-the-promethean-detail.html (with Joomla! SEF on).
In file: components/com_virtuemart/controllers/productdetails.php
around line: 350 is:
$this->setRedirect (JRoute::_ ('index.php?option=com_virtuemart&view=productdetails&virtuemart_product_id=' . $data['virtuemart_product_id']), $msg);
It should be:
$this->setRedirect (JRoute::_ ('index.php?option=com_virtuemart&view=productdetails&virtuemart_product_id=' . $data['virtuemart_product_id'] . '&virtuemart_category_id=' . $data['virtuemart_category_id']), $msg);
This line was missing:
'&virtuemart_category_id=' . $data['virtuemart_category_id']
