PDF invoice download OK

When I want to manually change the order status in VirtueMart is directed to the main panel of Joomla. He should change the status such as sent and to inform the customer.
Do you have any idea how to solve this problem?

Is there a solution to this problem?

well .. it is actually your problem as no one else has this problem 

JS errors in console? 3rd party ext. interfering? Tried different browsers/computers?
proper Joomla link to com_virtuemart root?
searched?  https://forum.virtuemart.net/index.php?topic=113837.0

How to improve the error for this update order status button? This is conflict js?
