I decided to backup my site this week-end and now it doesn't work.
I get this error:
Could not load file or assembly 'DotNetNuke.DNNTreeNavigationProvider' or one of its dependencies.
The entire error message is below. I tried copying the .dll files or copying the web.config to restart the application but that didn't work.
Server Error in '/' Application.
