Hi, I recently upgrade a customer from 8.2 R04 to 8.5 R05 and after upgrading user cannot not edit any maillings.
Everything else works seemingly fine, but when opening any mailing and pressing edit it's starts to load and never stops.
I've tried checking the log, but cannot see anything related.
I have added symmetrickey and secret to web config.
They are running the service netserver in default web site and web/service on a seperate site.
They do not use Service.
Any tips on what to do?
