I am working in DNN 9 for some reason the PersonaBar is no longer showing up. I am getting the error below.

I have already check newtonSoft.json and it is pointing to 7.0.0

This issue was due to System.Web.Http being missing from the project. I resolved this issue by updating references.

This is pretty close, I had to update my web.config and corresponding dlls in Bin folder for persona bar to start working.
