    tree load issue after upgrade

    Extending Umbraco and using the API
    Umbraco 7

    I have just upgraded umbraco to 7.10.3. When i hit the backoffice the trees do not load and in the log file i get:

    ERROR Umbraco.Web.Editors.SectionController - Unhandled controller exception occurred System.AggregateException: One or more errors occurred. ---> System.ArgumentNullException: Value cannot be null.

    I have seen similar issue on this post

    They are using unity I am using ninject as ioc container. Has anyone had this issue before? Any suggestions?

    Regards

    Ok so got to bottom of this. I removed everything in tree.config. I also removed old version of diplo log. Then rebuilt site. That updated the tree.config and site came up properly. I then installed latest diplo log viewer using nuget and its all good.

    Possibly, maybe the older version was using different tree interface ??
