404 Error When Viewing Invoices

Hello



I'm in the process of upgrading to V4 and I've come accross a problem.



When I go into View Orders and click on a specific order to look at it, I'm getting a 404 error.



Would anyone know why this might be?



Many thanks

Panic over…



I contacted my server hosts who found out it was to do with cookies and security.



All is working fine now!
