    Actually found a solution in the forums though I'm wondering why this would happen.

    Hi James,

    I'd love to help, but to be honest, I've no idea :) I've not changed significantly any of the code that generates the tree for a long time.

    I haven't tested it much on 7.4.0 beyond the RC, where it worked. Just out of curiosity I downloaded Umbraco 7.4.1 and rand the default site using SQL CE and then installed 2.2.4 via Nuget and it worked - didn't get any NULL reference exceptions.

    Is yours a new site or is it an upgrade of an existing site?

    It's a new build but we have gone through a few updates during the build process.

    I wonder if it is somehow due to us already using Autofac?

    Hi James,

    We have seen the same issue with Autofac. Registering the diplo trace viewer dll should do the trick.

    builder.RegisterApiControllers(Assembly.Load("Diplo.TraceLogViewer"));

    We have seen this with other packages that create custom trees as well (LeBlender, Umbraco Forms,...)

    Thanks Dave, yeah that's how I got it sorted.

    Has the tree config changed recently? I wonder whether my upgrade skipped the file due to prior changes.
