I have done a default installation of Magento 2.2.5 CE and when I click on an order in the Magento Admin I get the following error:
“Order View. Information changes have been made to this section that have not been saved. This tab contains invalid data. Please resolve this before saving”.
The problem is that I haven’t done any messing with the back end code and its a default install. Where am I going wrong? There doesn’t seem to be any other error messages. (I haven’t turned on developer mode). When I go into the Module Manger there are no modules listed so I don’t think its that. I don’t have any extension installed.
I’m baffled. Any help greatly appreciated.

Disabling module Temando_Shipping fixed that
Check the PHP Log.
you’ll must find an error log.
try to resolve the log error first. Also you can check your installed module, It might chances they’re conflicting.
