when I update or delete orders I will redirected to the main joomla admin page - without any change.
VM 3.0.10
Joomla 3.4.5
vm3.0.11
Hi,
I just installed 3.0.12
Same issue...
I've several 3.0.x sites - the issue occurs only on some of them. So I cleared all order tables manually.
Now it works again...
Seems that some order data was corrupted.
