I just updated one of my sites to version 6.8.1 and the page adminorders.php looks like a mess. Was there some other css file that I was supposed to upload?

There has been a complete overhaul of the adminorders page. It now uses a completely table-less design. The orders page now performs much better on smaller devices using responsive design methods, and has a leaner, more modern appearance for all devices. All admin pages also now include a style sheet "vsadmin/ectadmincustom.css". This style sheet does not normally exist, but can be created by yourself to customize areas of the admin if you require.

I updated one of our sites to 6.8.1 a couple of weeks back and it looked like a dogs dinner. On hitting Ctrl+F5 it was fine
