Upgraded a site from Relate 1.0 to 2.0 and now am getting the following error:
[NullReferenceException: Object reference not set to an instance of an object.]
EPiServer.PlugIn.AssemblyTypeInfo.UseCustomLoader(Type type, PlugInAttribute matchAttribute, ArrayList list) +60
After looking at reflector I belive the issue to be with either of these lines:
IUser currentUser = Settings.DefaultSecuirty.CurrentUser;
ISite currentSite = SiteHandler.Instance.CurrentSite;
But that's as far as I've gotten.
Have you tried to check the Event Viewer? I think you can find some clues there.
Thanks for the idea but I wasn't getting much out of error logs.
In the end I found there were a couple of other issues too which indicated that the database migration wasn't 100% successful. So did that again from the original version 1.0 site and connected the upgraded database from the second attempt and all is working. So most likely a few things in the db weren't migrated over correctly.
