After upgrade from Joomla 3.10.11 to Joomla 4.2.9 the following error occurs when ordering:
vmError: vmTable store insertObject #__virtuemart_order_userinfos Field 'modified_on' doesn't have a default value INSERT INTO `jos_virtuemart_order_userinfos`
In backend order is visible, but no user info present.
I've copied the Joomla 3 site to a subfolder, ordered a product to make sure everything was working. Order was placed normally. After upgrade to Joomla 4, the error occured.
